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.
