Doing peak current mode on the UCD is pretty complicated. There are lots of bits to configure. You need to start with the EVM code here: www.ti.com/.../UCD3138FW-PSFB Once you have that, adjusting the switching frequency to 200 kHz is easy.

This has been here for a while. I'll assume that the EVM code answered your question satisfactorily.
