160W DC DC Converter

TI suggests a design to perform this task. UCC28951 at 93%. What is your budget?

Without knowing spacial and size constraints, i put forward two transistor forward with synchronous rectifiers.

Or possibly full bridge with bootstrap primary drive, and sec with sync rects.

Or possibly even Full bridge with current doubler output rectifier, and sec sude sync rects.

Choice of the above three woudl depend on size and spacial constarints, and sales volume f the product.

You could even go two or three interleaved flybacks with sync rect outputs, in parallel, with mitigation cctry for load sharing purposes.

apologies, charring cross station internet is very slow today, and i woudl give further detail if it wasnt so slow...will chime back in later

any recomentation for IC part no

Hi,

most SMPS IC manufacturers provide online selection tools, where you input all your requirements and it gives you part numbers.

I´m a professional electronics designer ... and I use the tools frequently.

This could be handled by a dual flyback, 100kHz each section, 180 deg out of phase
