Maxim Integrated MAX5941A
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.| Part No. | MAX5941A |

GENERAL DESCRIPTION
These devices also feature power-mode undervoltage lockout (UVLO) with wide hysteresis and powergood status outputs. The MAX5941A/MAX5941B also integrate all the building blocks necessary for implementing DC-DC fixedfrequency isolated power supplies. These devices are a current-mode controller with an integrated high
