PMP20850
3.3V/15A 有源钳位正向参考设计
PMP20850
概述
This reference design is a 50W active clamp forward converter with synchronous rectification on the secondary side. The design provides an isolated, 3.3V/15A output from a standard telecom -36V to -72V input at >91% efficiency. PMP20850 utilizes a self driven, synchronous rectifier which requires no secondary gate driver which minimizes cost and improves efficiency. This device also features programmable dead-time, which is fine tuned to maximize efficiency of the design. Output voltage regulation is based on current mode control, simplifying loop compensation. PMP20850 features a catalog transformer, minimizing the cost of magnetics in the design.
