General Description
The MAX8833 high-efficiency, dual step-down regulator is capable of delivering up to 3A at each output. The device operates from a 2.35V to 3.6V supply, and provides output voltages from 0.6V to 0.9 x VIN, making it ideal for on-board point-of-load applications. Total output error is less than ±1% over load, line, and temperature.
