PMP9563
PoE 4 类高效有源钳位正向转换器
PMP9563
概述
This reference design is a Power Over Ethernet (POE) active clamp forward converter. It features the TPS23754, which is a combination of a POE Powered Device (PD) controller and PWM controller. CSD19534Q5A FETs are used for high efficiency synchronous rectification. The input accepts standard Type 2 POE voltage of 42.5VDC-57VDC or a 36VDC-57VDC auxiliary voltage. The output power is an isolated 12VDC at 1.9A with PoE input or 12VDC at 2.5A with auxiliary input.
