Download the MAX5942B datasheet PDF.
This datasheet also covers the MAX5942A variant, as both devices belong to the same ieee 802.3af power-over-ethernet interface/pwm controller family and are provided as variant models within a single manufacturer datasheet.
General Description
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.
Note: The manufacturer provides a single datasheet file (MAX5942A_MaximIntegratedProducts.pdf) that lists specifications for multiple related part numbers.

r Power Devices General Description 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. The MAX5942A/MAX5942B 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 hysteresi
