Microchip PD70211ILQ-TR

Контроллер (PD), DC/DC802.3at (PoE+), 802.3af (PoE)

Overview

The PD70211ILQ-TR front-end includes an advanced classification block that supports 2, 3, 4, and 6 event classification. Using the SUPP_Sx pins, it also identifies which of the four pairs of the cable actually receives power and generates appropriate flags. The IC features an internal bleeder for discharging the input capacitor of the DC/DC converter rapidly, so as to ensure fast re-detection and port power-up in case of sudden removal and re-insertion of the Ethernet cable into the RJ-45. The advanced PWM current mode section supports synchronous Flyback and Active clamp Forward topologies, as well as Buck, Boost etc...
