Hi 

I have a customer looking to implement a power supply design:

AC input

Output DCDC 12v 100A

Could you recommend a suitable ref design?

    Hi

    I assume you need an 85Vac to 265Vac input voltage range?

    The output is 1.2kW so it will most likely need a PFC front end to converter the AC line to a 380V to 400V BUS and then a phase shifted full bridge to converter the PFC DC voltage down to 12V through a step down isolation transformer.

    The UCC28180 is an 8 pin CCM PFC controller which can be used up 10kW and the UCC28070 is a two channel interleaved CCM PFC which is also suitable for high power PFC designs.

    The UCC28951 is the latest version of the PSFB controller and is very popular in this application space especially for CV and CC modes of control.

    Some suitable designs are below, the Q1 is automotive qualified devices.
