Input 115VAC / 400 Hz, Power Supply Design (10W)


Looking forward to design power supply as per below specification:

Required Output Power: 10 Watt

Input Voltage: 115VAC ± 20%

Input Frequency: 400 ± 20%

Output Voltage: +3.3VDC

Power Factor: >0.8

Efficiency: >75%

I am wondering if you can help to design power supply for 10W.

The most important aspect here is input frequency is 400Hz.

Please suggest the best suitable solution for above requirement.

In our past designs, LT1248 was used past.
