General Description

The MAX15003 is a triple-output, pulse-width-modulated (PWM), step-down DC-DC controller with tracking and sequencing capability. The device operates over the input voltage range of 5.5V to 23V or 5V ±10. Each PWM controller provides an adjustable output down to 0.6V and delivers up to 15A for each output with excellent load and line regulation. The MAX15003 is optimized for high-performance, small-size power management solutions.
