UCD3138PSFBEVM-027: UCD3138 & Fusion Digital Power Designer VBUS and Fs limits

Part Number: UCD3138PSFBEVM-027
Other Parts Discussed in Thread: UCD3138

Hello,

I would like to use the UCD3138 for a new design of Phase Shifted Full Bridge.

In this design the Vbus is 800V and the Fs should be around 70kHz.

I am trying to configure these values in the Fusion Digital Power Designer, and it is not possible because they are out of range.

Can you help me to deal with this problem?

Thank you.

    Hello,

    It is not simple answer. 

    You can change frequency from FDPS. 

    But you need modify your voltage scaler in hardware. Refer to EVM schematic, you can scale voltage the same as EVM for your Vout, Vin, and current.
