MAX8805W Overview
Description
The MAX8805W/MAX8805X/MAX8805Y/MAX8805Z high-frequency step-down converters are optimized for dynamically powering the power amplifier (PA) in WCDMA or NCDMA handsets. The devices integrate a high-efficiency PWM step-down converter for mediumand low-power transmission, and a 60m Ω typical bypass FET to power the PA directly from the battery during high-power transmission.
