Part Number: UCC28C54 Other Parts Discussed in Thread: UCC28781 , LM5023 , UCC28600 , UCC2801 , UCC28630 Tool/software: I am planning to make 200W SMPS based on QR Flyback topology with Sic Mosfet .
So, can you please help me to understand the challenges…
Part Number: UCC28C54 Hello,
I'm using UCC28C54 with an input voltage of 1000V max.
I used a resistors voltage divider so the VDD input voltage is 20V.
I'm currently investigating the situation of reverse polarity connection in the HV input. I couldn…
Part Number: UCC28C54 Tool/software: Hi Team,
in DS at table 7-1 it seems that the UCC28C54DR can work with a low frequencies as low as 10kHz.
in our design we are using 2.2nF and around 70kOhm resistor but when playing around with the resistor values…
Part Number: UCC28C54 Hi
I used the WEBench designer for an AC/DC design using the UCC28C54, and got the design in the attached PDF. I built it according to the design, but the UCC28C54 does not start. Digging into the details I notice two things…
Part Number: UCC28C54 Other Parts Discussed in Thread: UCC28C56EVM-066 Tool/software: Hello,
My customer wants to design a product using UCC28C54 that supports the following conditions:
1) Input: 750Vdc 2) Output: 12Vdc/100W
Q1. Is it possible to…
Part Number: UCC28C54 Other Parts Discussed in Thread: UCC28750 , Tool/software: Customer was looking for a flyback solution: Vin= 36V-60V, Vout=24V/3A, 6A overcurrent threshold, with short circuit protection function and input UVLO function(36V) required…
Part Number: UCC28C54 Tool/software:
Hello.
I am planning to design a 108W Flyback Converter using the UCC28C54 IC.
Would this IC be suitable for this application?
The input and output specifications are as follows:
Input voltage: 750V Output…

Tool/software:
Hi,
I would like to ask about EMI tests. I have cca 100W flyback without pfc, with UCC28C54 and Synchronious rectifier. Switching frequency cca 95 kHz. I tried to handle peaks caused by switching frequency by…
Part Number: UCC28C54-Q1 Tool/software: Hi.
I'm currently working on an isolated power supply. Based on what I looked up flyback topology seems to fit my specs (Vin ~ 24VDC, Vout = 24VDC, Iout = 5A).
I came across a few controllers - UCC28C4x and…
Part Number: UCC28C54 Hi
I have made a design with the UCC28C54 following the typical application example and design guide lines from page 26 on in the datasheet below. Please see the attached schematics. It seems to work as intended apart from the…
