Description

The PMP5410 is 280W 48V-input/14V-output isolated DC/DC converter reference design based on Phase Shifted Full Bridge power topology. It is targeted at telecom applications to supply a stable and well-regulated 14V backplane in base station power trains. The design features UCC28950 controller operating from the primary side (48V input side) and employs peak current mode control to drive the 4 bridge MOSFETs on the primary side and also the synchronous-rectification MOSFET control on the secondary side. The design accepts a wide input voltage of 36V to 57V and delivers up to 20A of output current at 14V.
