Texas Instruments TPS2372-3 | Demoboard PMP23366

Beschreibung

This design implements a Power over Ethernet (PoE) Class 6 Powered Device (PD) with dual redundant PoE inputs and smooth transition between these inputs and a an auxiliary input. Two TPS2372-3 PD controllers are utilized for high power PoE control up to 51W. A 5V at 9A active clamp forward converter is implemented with the PWM portion of a TPS23734 IC. An INA237A provides input voltage/current/power/temperature measurements via I2C.

Eigenschaften
