What should we promote to customer as they require HV-buck(370Vdc input, 110Vdc/1A output)

Mike

Two recommendations we have are

1. DCM flyback controllers like UCC28700 configured as a buck like PMP10937. The valley switching and integrated compensation enable it to have high performance

2. Current mode PWM controller like UCC28C42 configured as a buck like PMP10783. These devices have a high amount of flexibility so they can help designer meet requirements.

Best regards

Eric,

I will try your suggestion and thanks for your kind help!
