结合100 -V型IEEE 802.3af PD和DC / DC控制器 INTEGRATED 100-V IEEE 802.3af PD AND DC/DC CONTROLLER
DESCRIPON
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 voltage, which is compatible with legacy systems.
