Description

This reference design demostrates full-function 1.2KW triple-rail digital power supply solution for telecom application. The input range is 36-60Vin and outputs are two 48V10A(Full bridge) and one 5.5V30A(active clamp). Synchrounous rectifiers are used in the design and the overall efficiency is up to 92%@full load. The full-feature digital solution includes soft start, power up/down sequencing,fast response to input dip, protection features as OVP, OCP, OTP and input UVLO. Other devices like LM34927, UCC27324, UCC27201 are also used to provide bias supply and drive the FETs.
