General 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.

Dual 200mA low-noise, high-PSRR low-dropout regulators (LDOs) for PA biaswww.DataSheet4U.com ing are also integrated.

Overview

19-0777; Rev 1; 10/07 600mA/650mA PWM Step-Down Converters in 2mm x 2mm WLP for WCDMA PA.
