MAX5941A - IEEE 802.3af-Compliant Power-Over-Ethernet Interface/PWM Controller

Description

The MAX5941A/MAX5941B integrate a complete power IC for powered devices (PD) in a power-over-ethernet (PoE) system.

The MAX5941A/MAX5941B provide a PD interface and a compact DC-DC PWM controller suitable for flyback and forward converters in either isolated or nonisolated designs.

19-3069; Rev 4; 6/06 EVAALVUAAILTAIOBNLEKIT IEEE 802.3af-Compliant Power-Over-Ethernet Interface/PWM Controller for Power Devices MAX5941A/MAX5941B General Description The MAX5941A/MAX5941B integrate a complete power IC for powered devices (PD) in a power-over-ethernet (PoE) system. The MAX5941A/MAX5941B provide a PD interface and a compact DC-DC PWM controller suitable for flyback and forward converters in either isolated or nonisolated designs. The MAX5941A/MAX5941B PD interface complies with the IEEE 802.3af standard, providing the PD with a detection signature, a classification signature, and an integrated isolation switch with programmable inrush current control. These devices also feature power-mode undervoltage lockout (UVLO) with wide hysteresis and powergood status outputs.
