Product Summary
The MAX17015A 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. The MAX17015A 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 MAX17015A has an internal 1A N-channel MOSFET switch. The applications of the MAX17015A include Digital Cordless Phones, Personal Communicators, Palmtop Computers, Hand-Held Instruments, PCS Phones, Wireless Handsets and Two-Way Pagers.
