TPS23770 Overview
The TPS23750 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 ponents. The TPS23770 is identical to the TPS23750 with the exception of the undervoltage lockout turn-on voltage, which is patible with legacy systems.
