General Description

The MAX15021 is a dual-output, pulse-width-modulated (PWM), step-down DC-DC regulator with tracking (coincident and ratiometric) and sequencing options. The device operates from 2.5V to 5.5V and each output can be adjusted from 0.6V to the input supply (VAVIN). The MAX15021 delivers up to 4A (regulator 1) and 2A (regulator 2) of output current. This device offers the ability to adjust the switching frequency from 500kHz to 4MHz and provides the capability of optimizing the design in terms of size and performance.

Benefits and Features
