Part Number: PMP21479 Hi,
Customer would like to check the operation and behavior of this EVM board with DC input range from 300Vdc to 450Vdc for the server power aux application. Do you have any component change suggestion for the PMP21479 schematic …
Part Number: PMP21479 Hi,
My customer would like to evaluate the PMP21479 with fixed output 12V. Would you please guide how to adjust the output voltage to 12V in the PMP21479 design? Customer wants to evaluate the performance of ACF.
Best regards,
Ra…

Part Number: PMP21479 Other Parts Discussed in Thread: UCC28780 , LMG3411R150 What are the trade-offs between using Gallium Nitride (GaN) versus Silicon (Si) FETs in an active clamp flyback?
Hiroshi-san
You are correct, in order to achieve small solution size and have high efficiency an active clamp flyback will have to be used instead of a QR flyback.
The size of the adapter is dependent on the switching frequency. To achieve small solution…
