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: 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 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: 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…
Part Number: UCC28C43-Q1 Other Parts Discussed in Thread: UCC28C43 , UCC28C53 , UCC28C59 Tool/software: I've been trying to simulate the design provided by the manufacturer, but I'm encountering issues. The output is consistently zero, although the feedback…
Part Number: UCC28C43-Q1 Other Parts Discussed in Thread: UCC28C43 Hello,
In the UCC28c43 datasheet ,COMP pin high level typical output voltage is mentioned as 6.8V, why it is greater than 5V (which is internal supply)
Part Number: UCC28C43-Q1 Other Parts Discussed in Thread: UCC28C43 , TPS40210 Hi Experts,
the device seems to have no feature to improve the light load efficiency, like pulse skipping. Can you confirm that there are better recommendations if this is a key…
Part Number: UCC28C43-Q1 To Application team,
I know that this parts has the spec of 0% duty cycle. However, there is no spec of minimum ON pulse width.
If IC has a blanking time built on IC itself, it should be equivalent to the minimum ON pulse width…
