TPS23770 Datasheet (Texas Instruments) - Integrated 100-V IEEE 802.3af PD and DC/DC Controller

TPS23770, Integrated 100-V IEEE 802.3af PD and DC/DC Controller

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 components.

The TPS23770 is identical to the TPS23750 with the exception of the undervoltage lockout turn-on v
