High-efficiency and low-cost 400W power supply design based on ADP1051

This reference design uses ADI's newly launched low-cost, highly integrated power chip ADP1051 to control the energy conversion from input to output. This power design takes efficiency and cost into consideration and designs a solution with the best efficiency and cost at a 400W power level. It is suitable for the power amplifier power supply system of wireless communication base stations and the railway power supply system in the industrial field. ADP1051 is a digital controller with a PMBus interface for isolated power supplies. Due to the excellent performance of ADP1051, this design has the characteristics of high reliability, high efficiency and high integration. In addition, this reference design also implements a series of monitoring functions, such as IOUT_OC, VOUT_OV, OT, VOUT_UV, input UVLO, reverse current protection, short circuit protection, etc. defined in PMbus.
