PMP10288 is a Class 4 POE, High-Efficiency, Active Clamp Forward Converter (3.3V) Reference Design

This post sponsored by Texas Instruments.

The PMP10288 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. CSD17501Q5A 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 3.3VDC at 6.9A with PoE input or 3.3VDC at 7.2A with auxiliary input.

PMP10288 has a power conversion efficiency of 90% at full load. It has low-gate-charge MOSFETs for high-efficiency synchronous rectification. Auxiliary power input is available.

The test report includes efficiency, ripple, load step, turn-on response, loop stability, and thermal plot.
