General Description
The MAX1760 is a high-efficiency, low-noise, step-up DC-DC converter intended for use in battery-powered wireless applications. It maintains exceptionally low quiescent supply current (100µA) despite its high 1MHz operating frequency. Small external components and a tiny 10-pin µMAX package make this device an excellent choice for small hand-held applications requiring the longest possible battery life.
