MAX1705 Datasheet (Maxim) - 1- to 3-Cell / High-Current / Low-Noise / Step-Up DC-DC Converters

MAX1705, 1- to 3-Cell / High-Current / Low-Noise / Step-Up DC-DC Converters

The MAX1705/MAX1706 are high-efficiency, low-noise, step-up DC-DC converters with an auxiliary linearregulator output.

These devices are intended for use in battery-powered wireless applications.

They use a synchronous rectifier pulse-width-modulation (PWM) boost topology to generate 2.5V to 5.5V ou
