My customer wants to find a PWM controller applicable for the condition-Vin=200~380V/ Vout=400V/ Pout=3KW.
Do we have suggested part for this? Thanks.

An "isolated boost" converter is commonly referred to as a flyback converter. Your requirements show high voltage on the primary (200 V<VIN<380 V), high power (3 kW), high current (7.5 A) compared to what can be expected from a flyback converter. Your requirements are sometimes met using a phase shifted full bridge (PSFB) topology and TI has many PSFB controller to choose from. Please start by visiting TI.com at PWM Controllers & Resonant controllers. Good luck with your design and thanks for connecting through E2E.
