Product Summary
The MAX1706EEE-T is a high-efficiency, low-noise, step-up DC-DC converter with an auxiliary linear regulator output. The device is intended for use in battery-powered wireless applications. It uses a synchronous rectifier pulse-width-modulation (PWM) boost topology to generate 2.5V to 5.5V outputs from battery inputs, such as 1 to 3 NiCd/NiMH cells or 1 Li-Ion cell. The MAX1706EEE-T has a 0.5A switch. It also has a built-in low-dropout linear regulator that delivers up to 200mA.
