MAX1533A, Main Power-Supply Controllers

The MAX1533A/MAX1537A are dual step-down, switchmode power-supply (SMPS) controllers with synchronous rectification, intended for main 5V/3.3V power generation in battery-powered systems.

Fixed-frequency operation with optimal interleaving minimizes input ripple current from the lowest input voltage
