com Dual PWM Step-Down Converter in a 2mm x 2mm Package for WCDMA PA and RF Power General Description The MAX8896 dual step-down converter is optimized for powering the power amplifier (PA) and RF transceiver in WCDMA handsets.
This device integrates a highefficiency PWM step-down converter (OUT1) for medium and low-power transmission, and a 140mΩ (typ) bypass FET to power the PA directly from the battery during high-power transmission.
A second highefficiency PWM step-down converter (OUT2) supplies power directly to a high PSRR, low output noise, 200mA low-dropout linear regulator (LDO) to power the RF transceiver.
Fast switching allows the use of smal...
