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 detec- tion signature, a classification signature, and an integrat- ed isolation switch with programmable inrush current control. These devices also feature power-mode under- voltage lockout (UVLO) with wide hysteresis and power- good status outputs. The MAX5942A/MAX5942B also integrate all the build- ing blocks necessary for implementing DC-DC fixed- frequency isolated power supplies. This device is a current-mode controller with an integrated high startup circuit suitable for isolated telecom/industrial voltage range power supplies. A high-voltage startup circuit allows the PWM controller to draw power directly from the 18V to 67V input supply during startup. The switching frequency is internally trimmed to 275kHz 10%, thus reducing magnetics and filter components. The MAX59412A allows an 85% operating duty cycle and can be used to implement flyback converters. The MAX5942B limits the operating duty cycle to less than 50% and can be used in single-ended forward converters. The MAX5942A/MAX5942B are designed to work with or with- out an external diode bridge in front of the PD. The MAX5942A/MAX5942B are available in 16-pin SO packages.
