Product Summary

The TPS23750PWPR is a DC/DC controller. The TPS23750PWPR integrates the functionality of the TPS23750PWPR 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 TPS23750PWPR is identical to the TPS23750PWPR with the exception of the under voltage lockout turn-on voltage, which is compatible with legacy systems. 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 TPS23750PWPR. The dc/dc controller section is designed to support fly back, forward, and no 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. The applications of the TPS23750PWPR include Wireless Access Points, VoIP Phones and Security Cameras.
