This reference design implements a Power over Ethernet (PoE) power device (PD) active clamp forward converter with 12-V and 2.1-A output. A TPS23734 PD, pulse width modulator (PWM) controller provides all the necessary functions to implement the PoE PD control and the PWM control for the active clamp forward converter. This design uses secondary side regulation (SSR) with an optocoupler feedback.
