Description
PD70211 is an advanced PD Interface IC with integrated switching (PWM) regulator control for Powered Devices in PoE applications.
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 currentmode section supports synchronous Flyback and Active clamp Forward topologies, as well as Buck, Boost etc. Features
Supports IEEE802.3af/at, HDBaseT and other 2pair/4-pair configurations
Wall-adapter support (Rear Aux method) PD detection & program.
