Brief Introduction of FAN7621BSJX or FAN7621

The FAN7621BSJX or FAN7621SJX is a pulse frequency modulation controller for high-efficiency half-bridge resonant converters.Offering everything necessary to build a reliable and robust resonant converter, the FAN7621B simplifies designs and improves productivity, while improving performance. The FAN7621B includes a highside gate-drive circuit, an accurate current controlled oscillator, frequency limit circuit, soft-start, and built-in protection functions. The high-side gate-drive circuit has a common-mode noise cancellation capability, which guarantees stable operation with excellent noise immunity. Using the zero-voltage-switching (ZVS) technique dramatically reduces the switching losses and efficiency is significantly improved. The ZVS also reduces the switching noise noticeably, which allows a small-sized Electromagnetic Interference (EMI) filter. The FAN7621B can be applied to various resonant converter topologies; such as series resonant, parallel resonant, and LLC resonant converters.

FAN7621B — PFM Controller for Half-Bridge Resonant Converters

Functional Description

1. Basic Operation: FAN7621B is designed to drive

high-side and low-side MOSFETs complementarily with

50% duty cycle. A fixed dead time of 350ns is introduced

between consecutive transitions, as shown in Figure 16.

Figure 16. MOSFETs Gate Drive Signal

2. Internal Oscillator: FAN7621B employs a current-

controlled oscillator, as shown in Figure 17. Internally,

the voltage of R T pin is regulated at 2V and the charging

/ discharging current for the oscillator capacitor, C T , is

obtained by copying the current flowing out of R T  pin

(I CTC ) using a current mirror. Therefore, the switching

frequency increases as I CTC increases.

Figure 17. Current Controlled Oscillator

3. Frequency Setting: Figure 18 shows the typical

voltage gain curve of a resonant converter, where the

gain is inversely proportional to the switching frequency

in the ZVS region. The output voltage can be regulated

by modulating the switching frequency. Figure 19 shows

the typical circuit configuration for R T pin, where the

opto-coupler transistor is connected to the R T pin to

modulate the switching frequency.

Figure 21. Internal Block of Control Pin

Protection: When the control pin voltage exceeds 5V,

protection  is  triggered.  Detailed  applications  are

described in the protection section.

Pulse Skipping: FAN7621B stops switching when the

control pin voltage drops below 0.4V and resumes

switching when the control pin voltage rises above 0.6V.

To use pulse-skipping, the control pin should be

connected to the opto-coupler collector pin.

6. PCB Layout Guideline: Duty imbalance problems

may occur due to the radiated noise from main

transformer, the inequality of the secondary-side leakage

inductances of main transformer, and so on. Among

them, it is one of the dominant reasons that the control

components in the vicinity of R T pin are enclosed by the

primary current flow pattern on PCB layout. The direction

of the magnetic field on the components caused by the

primary current flow is changed when the high-and-low

side MOSFET turns on by turns. The magnetic fields with

opposite direction from each other induce a current

through, into, or out of the R T pin, which makes the turn-

on duration of each MOSFET different. It is strongly

recommended to separate the control components in the

vicinity of R T pin from the primary current flow pattern on

PCB layout. Figure 28 shows an example for the duty-

balanced case. The yellow and blue lines show the

primary current flows when the lower-side and higher-

side MOSFETs turns on, respectively. The primary

current does not enclose any component of controller.

In addition, it is helpful to reduce the duty imbalance to

make the loop configured between CON pin and opto-

coupler as small as possible, as shown in the red line in

Figure 28.

GENERAL GENERAL DESCRIPTION The AD7228 contains eight 8-bit voltage mode digital-to- analog converters (DACs), with output buffer amplifiers and interface logic on a single monolithic chip. No external trims are required to achieve the full specified performance for the device. Separate on-chip latches are provided for each of the eight DACs. Data is transferred into the data latches through a common 8-bit, TTL/CMOS-compatible input port (5 V). The A0, A1, and A2 address inputs determine which latch is loaded when WR goes low. The control logic is speed compatible with most 8-bit microprocessors. Specified performance is guaranteed for input reference voltages from 2 V to 10 V when using dual supplies. The device is also specified for single-supply operation using a reference of 10 V. Each output buffer amplifier is capable of developing 10 V across a 2 kΩ load. The AD7228 is fabricated on an all ion implanted, high speed, linear-compatible CMOS (LC2 MOS) process, specifically developed to integrate high speed digital logic circuits and precision analog circuits on the same chip. PRODUCT HIGHLIGHTS 1. The single chip design of eight 8-bit DACs and amplifiers allows a dramatic reduction in board space requirements and offers increased reliability in systems using multiple converters. The PDIP, CERDIP, and SOIC pinout is aimed at optimizing board layout with all analog inputs and outputs at one side of the package and all digital inputs at the other. 2. The voltage mode configuration of the DACs allows single supply operation of the AD7228. The device can also be operated with dual supplies giving enhanced performance for some parameters. 3. The AD7228 has a common 8-bit data bus with individual DAC latches, providing a versatile control architecture for simple interface to microprocessors. All latch enable signals are level triggered and speed compatible with most high performance 8-bit microprocessors.

Cutting Edge Innovation with FPGAs

Artificial intelligence, as it turns out, is just too useful to remain up in the cloud. Demand for local AI processing is increasing as smart devices want the intelligence without the internet connection. Everyone is talking about AI at the Edge and Terasic is no exception. In fact, it’s their theme for this summer’s InnovateFPGA design contest.

Teams from all over the world are currently submitting their project proposals to show off their takes on artificial intelligence. Various cash prizes and Terasic development kits will be awarded to the best projects at the regional and global levels.  The top three teams from each region also receive a trip to Tianjin, China to present their designs at the grand finals during the 2019 International Conference on Field-Programmable Technology.

One of the criteria that teams will be judged on is their demonstration of Intel’s three FPGA virtues. These are the benefits that FPGAs bring to processor systems: boosting performance, adapting to changes, and expanding I/O. With the theme of AI, performance will likely be a big focus as FPGAs outperform traditional processors on the matrix operations common in neural networks, machine vision, and other related applications.

This year’s contest offers developers the choice of two Intel Cyclone V SoC platforms to build their innovative FPGA designs on. The DE10-Nano Kit, the star of last year’s contest, returns and is now accompanied by the new OpenVPN Starter Kit, a PCIe card with nearly 3x the logic elements of the DE10-Nano. Participants are also welcome to use Intel’s OpenVPN deep learning toolkit which just so happens to pair quite well with Terasic’s starter kit of the same name.

Raspberry Pi 4 vs Raspberry Pi 3 “A New Slice of Pi ”

Raspberry Pi 4 vs Raspberry Pi 3, 
 semibing.com

Who is ready for another piece of pi? Every time a new Raspberry Pi comes out, there is excitement from all angles. This time is no different, in fact, it might be more exciting. Back in January, the raspberry pi foundation mentioned: “This will be the last Pi of its kind”. The new Raspberry Pi 4 Model B has launched today, with some new and much-anticipated features. Really amazing!

The Raspberry Pi 4 Model B is the first pi with a 28nm processor. Moving to the 28nm from the 40nm based products allows the new pi to utilize a much more powerful processing core and have better I/O performance. This new pi could be a full PC replacement. Every engineer and/or maker in the world requires a dual monitor display for desktops. Let’s see how the new pi can increase productivity and allow for writing python and web browsing on two separate screens.

Here is the dirt…. What has changed,hoho? What is missing? How has the pi foundation listened?

    • Operating temperature 0–50°C
  • Compliance:
  • Production lifetime:
    • The Raspberry Pi 4 Model B will remain in production until at least January 2026.

How do I think about this new Raspberry Pi ???

In my own opinion, adding the USB C port was a great move. Hopefully, the rest of the world will adopt this strategy. I am ready to be done carrying so many cables with me. They have also increased the input current to 3 Amps to handle the increased power needed to run.

Great Connectivity – the adoption of Bluetooth 5.0 has been incorporated, which will give faster connection speeds along with a more stable Bluetooth experience. Replacing 2 of the 4 existing USB 2.0 ports with USB 3.0 gives expanded capabilities and they have added true Gigabit Ethernet.

Incorporating two micro HDMI ports instead of one full size port gives the capability to utilize two monitors on your pi or allow for dual monitors in a kiosk or display stand. This was asked for by many of the pi users and the Raspberry Pi foundation listened. The option to output 4K video is another addition that was not on any pi previously. You can have one video output at 4K at 60fps or two at 4K at 30 fps.

Now for the options, yes this has options just like buying a new car. You will have the ability to select the memory of your choice. 1GB, 2GB, and 4 GB are the choices available.

This new Pi will enable you to create to the n’th degree with the increased speed, functionality, and memory.

Upgrading from a Raspberry Pi 3 to a Raspberry Pi 4
Over the next couple of weeks, we will be creating blogs and how to articles for detailed solutions on how to upgrade from a Raspberry Pi 3 to a Raspberry Pi 4. For now, here are some items you will need to think about:
1) Power supply – The new Raspberry Pi 4 Model B requires two changes. First the connector is now USB C and the board requires an amperage increase to 3A. Here is a link to supplies that you can use. We have listed both standalone and corded versions just in case you already have a USB C cable lying around: Click here.
2) HDMI – The new Raspberry Pi 4 Model B has micro HDMI ports. If all you have is standard HDMI cables then you will need either an adapter or a new cable.
3) USB – While there are two USB 2.0 connectors on the new Raspberry Pi 4 Model B, one of the best new features is support of USB 3.0 and in order to take full advantage you will want USB 3.0 cables. Pay particular attention to what type of cable you need since you will be using a USB A male to plug into the Pi, you may need an A, B or C male connector on the other end depending on your design. You can find all of them here.
4 Gigabit Ethernet – Most Ethernet patch cables will work just fine but some people only have the older Cat 5 cables. If you are having speed issues you may want to look at either Cat5e or Cat6 cables.
Product Highlight: Raspberry Pi 4 Model B – Raspberry Pi’s first 28 nm-based product moves to a more modern process node making Raspberry Pi 4 a true PC replacement
