1kW Triple-Rail Isolated DC/DC Digital Power Supply for Telecom (-8V@.25A)
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.
