MAX5942A Datasheet (Maxim) - IEEE 802.3af Power-Over-Ethernet Interface/PWM Controller

MAX5942A, IEEE 802.3af Power-Over-Ethernet Interface/PWM Controller

The MAX5942A/MAX5942B integrate a complete power IC for powered devices (PD) in a power-over-ethernet (PoE) system.

The MAX5942A/MAX5942B provide a PD interface and a compact DC-DC PWM controller suitable for flyback and forward converters in either isolated or nonisolated designs.
