Product Summary

The MAX1700EEE is a high-efficiency, low-noise, step-up DC-DC converter intended for use in battery-powered wireless applications. The MAX1700EEE uses a synchronous-rectified pulse-width-modulation (PWM) boost topology to generate 2.5V to 5.5V outputs from battery inputs such as one to three NiCd/NiMH cells or one LiIon cell. The MAX1700EEE has an internal 1A, 130mΩ N-channel MOSFET switch and a 250mΩ P-channel. The applications of the MAX1700EEE include Digital Cordless Phones, Personal Communicators, PCS Phones Palmtop Computers, Wireless Handsets, Hand-Held Instruments and Two-Way Pagers.
