Other Parts Discussed in Thread: UCC28C40-Q1, UCC28C41
Hi team,
I'd like to check my understanding about the difference between UCC28C41-Q1 and UCC28C40-Q1. UCC28C41-Q1 can only be operated with input from LV(12V battery as an example), while UCC28C40-Q1 works for HV application as well with a start-up circuit, is that right? Can you help me understand why 100% duty cycle is necessary for HV input?
I've read slyy164 UCC28C4X selection guide for automotive isolated DCDC auxiliary power application but not fully understand. Could you please explained more on the applications limitation of different UVLO combinations?
Thanks,
Scarlett
