Description
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.
Features
- Integrated PD and PWM controller
- Power Conversion Efficiency of 90% at full load
- Low gate charge MOSFETs for high efficiency synchronous rectification
- Auxillary power input available
- Test report includes efficiency, ripple, load step, turn-on response, loop stability, and thermal plot
