The MAX1817 is a compact, high-efficiency, dual-output step-up converter for portable devices that provides both the main logic supply and the LCD bias. The device operates from an input voltage of +1.5V to +5.5V, allowing the use of 2- or 3-cell alkaline batteries, or 1-cell lithium-ion (Li+) batteries.

The MAX1817's main regulator supplies 125mA at either a preset 3.3V or an adjustable 2.5V to 5.5V output voltage with up to 88% efficiency. A 0.1µA shutdown state also minimizes battery drain. The MAX1817's secondary step-up converter provides the LCD bias voltage and is adjustable up to +28V.

Other features include a fast switching frequency to reduce the size of external components and a low quiescent current to maximize battery life. Both outputs can be independently shut down for improved flexibility.

The MAX1817 is supplied in a compact 10-pin µMAX package. The MAX1817 evaluation kit (MAX1817EVKIT) is available to speed up design.
