PD70224 Overview
PD70224 IdealBridge™ Dual MOSFET-Based Bridge Rectifier Introduction PD70224 is a dual pack of MOSFET-based full-bridge rectifiers. It contains low-RDS 0.16 Ω N-channel MOSFETs for much higher overall efficiency and higher output power, particularly when used in Powered Devices for Power over Ethernet (PoE) applications. The entire drive circuitry for driving the MOSFETs is on-chip, including a charge pump for...
