PD70211 is an advanced PD Interface IC with integrated switching (PWM) regulator control for Powered Devices in PoE applications.

Product Detail

PD70211 is an advanced PD Interface IC with integrated switching (PWM) regulator control for Powered Devices in PoE applications. It supports IEEE802.3af, IEEE802at, HDBaseT and general 2/4-pair configurations. The PD70211 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...
