MAX5973 Description
The MAX5973 protects individual slave phases of a phase redundant DC-DC converter. The power protection functions prise an electronic circuit-breaker controller driving an external n-channel MOSFET at the step-down power input, and an internal 3.3V switch for the slave phase-controller power. To protect the output bus, an “ideal diode” controller drives an external n-channel MOSFET at the slave phase output.
