Part Number: UCC28C54-Q1 Tool/software: When starting a PSPICE simulation an error message pops up indicating the RPC (remote procedure call) server is unavailable. However, the RPC server and RPC locator are both set to automatic and both are running…
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-Q1 Other Parts Discussed in Thread: UCC28C54 Tool/software: Hello,
I recreated my simulation circuit for the UCC28C54 device in PSPICE after the model generated errors in LTSPICE. After completing the schematic and setting up what…
Part Number: UCC28C54-Q1 Hi
In the datasheet page 35 a crossover frequency of 625 Hz is selected for the typcial application design exemplified in the datasheet, and then the error amplifier mid-frequency gain is determined to 14,6 V/V. How do I choose…
Part Number: UCC28C54-Q1 Other Parts Discussed in Thread: UCC28C54 Hi
I read the article on common mistakes in flyback power supplies (linked below) with great interest and took special notice about the OVP and OCP functionality. Then I dove into…

Hi
I have an AC/DC flyback converter designed for 240V AC --> 12V 84W DC. It's based mainly off a webench design and the datasheet typical application design. With a small load it outputs 12.2 volts. With 10 W load it outputs…
Hi
Here is a link to your datasheet, and the equations are (4) and (5) on page 27 https://www.ti.com/lit/ds/symlink/ucc28c54-q1.pdf?ts=1712065214192&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FUCC28C54-Q1
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…
Joginder,
UCC28C54-Q1 , is an automotive current mode PWM that is tailored for high-voltage (HV) HEV/EV and industrial applications. It is intended to be used in applications operating from ~1kV+ and TI has developed an EVM demonstrating it's used in…
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…
