Part Number: UCC28C43-Q1 Other Parts Discussed in Thread: UCC28C43 Tool/software: Hello Folks,
We are using the UCC28C43 device in a flyback application in our product and we have noticed that for a high input voltage and typical load, the controller…
Part Number: UCC28C43-Q1 Other Parts Discussed in Thread: UCC28C43 Tool/software:
current sense gain from the UCC28C43 datasheet is typ 3V, but in the IC block diagram gain section did not shown, CS pin input is directly going to the PWM comparator.…
Part Number: UCC28C43-Q1 Tool/software: Hi E2E,
We are designing a power supply using UCC28C43-Q1.
In previous designs,the negative feedback input to the COMP is after optocoupler isolation .
We want to know if there is a way to directly feed the output…
Part Number: UCC28C43-Q1 UCC28C43QDRQ1's datasheet suggests that the RT resistance should be configured above 1kΩ.
However,we have using the RT/CT combination of 820R/1nF to produce a square wave with a duty cycle of 50% at 1MHz.
I hope to confirm…
Part Number: UCC28C43-Q1 Dear TI team,
I am using UCC28C43-Q1 IC for my Flyback converter application. I want to implement Enable/ Disable signal to Flyback converter.
In datasheet, it shows only MOSFET and Disable signal from micro-controller. I have…
Part Number: UCC28C53-Q1 Other Parts Discussed in Thread: UCC28C43 Hi Hong,
I dont see UCC28C43/53 support for Flyback PSR in Webench. I hope it is okay to design PSR wit Aux winding. pls confirm.

Part Number: UCC28C43-Q1 Hello colleagues,
My customer has an issue with UCC28C43-Q1, t he controller is part of a flyback converter, as shown in the following picture:
The voltage of the Aux winding is regulated.
During stability studies, we noticed that…
Part Number: UCC28C43-Q1 Hello,
I am looking for some support using the COMP pin to disable the PWM IC. I use the P-MOSFET to pull COMP to GND as suggested in the datasheet. The voltage of COMP initially stabilized at 3.38V. Then P-MOSFET is turned on,…
Part Number: UCC28C43-Q1 Hi Team,
I have referred the following schematic for the design of fly-back converter using SiC MOSFET @ 400kHz frequency. The circled part i.e., external current buffer circuit is designed for C2M1000170D.
Q1. If I use C3M0120065D…
