General Description

The MAX1630–MAX1635 are buck-topology, step-down, switch-mode, power-supply controllers that generate

logic-supply voltages in battery-powered systems. These high-performance, dual/triple-output devices include on

board power-up sequencing, power-good signaling with delay, digital soft-start, secondary winding control, low

dropout circuitry, internal frequency-compensation net works, and automatic bootstrapping.
