TPS23750PWP Datasheet PDF - TI

●The TPS23750PWP is an Integrated IEEE 802.3af PD Controller with a primary side DC/DC PWM controller. The designer can create a front-end solution for PoE-PD applications with minimum external components. The PoE front end has all the necessary IEEE 802.3af functions including detection, classification, under-voltage lockout and inrush control. The PoE input switch is integrated within the TPS23750. The DC/DC controller section is designed to support flyback, forward and non-synchronous low-side switch buck topologies. The external switching MOSFET and current sense resistor provide flexibility in topology, power level and current limit. The full-featured DC/DC controller includes programmable soft start, hiccup type fault limiting, 50% maximum duty cycle, programmable constant switching frequency and a true voltage-output error amplifier. Additional protection features provide for robust designs.
