Product Summary

The TPS23750PWPR is a DC/DC controller. The TPS23750PWPR integrates the functionality of the TPS2375 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, undervoltage lockout and inrush control. The PoE input switch is integrated within the TPS23750PWPR. The dc/dc controller section is designed to support flyback, forward, and nonsynchronous low-side switch buck topologies.
