Hello ti team
we have developed a simulation model for flyback 100kHz application. all the recommended values has been placed as per datasheet.
but it gives convergence error.
can you help me in resolving this …
Part Number: UCC28C56H Other Parts Discussed in Thread: UCC27714 , LM5155 Tool/software: Hi,
I am designing a high-voltage synchronous boost converter with an output of DC110V and need a suitable control IC.
However, most control ICs have insufficient…
Part Number: UCC28C56H-Q1 Tool/software: Good morning Team,
I am working on power supply design for Inverter. So, decided to go with Flyback for HV DC-DC converter. Could you suggest me PWM controller IC's for the below specifications.

Hi Hong,
Thanks for the response .
I have tested the below ckt recently whcih is designed accordance with Ti webench and UCC28C56H Q1 EVB references. pls verify.
I have observed huge VDS spike across the Flyback switch, also the Vout of flyback is held…
Part Number: UCC28C56H-Q1 Other Parts Discussed in Thread: UCC28C56H , UCC24612 Dear Team,
I am designing Flyback with UCC28C56H-Q1 for the below specs. As you can see the Transient voltage at input side is for 5sec and remaining times the Steady state…
Part Number: UCC28C56H-Q1 Other Parts Discussed in Thread: UCC28C56EVM-066 I was Testing UCC28C56EVM-066 Evaluation board for my project but while testing PWM IC gone bad. So I need sample parts of UCC28C56H-Q1 immediately to resume my testing.
