This reference design implements a Power over Ethernet (PoE) power device (PD) active clamp forward converter with 24-V and 2.5-A outputs. A TPS23730 PD with integrated pulse width modulator (PWM) controller provides all the necessary functions to implement the PoE PD and PWM control for the active clamp forward converter. This design uses secondary-side regulation (SSR) with an optocoupler feedback.
