MAX77179 - Maxim Integrated

MAX77179 High-Bandwidth LTE/WCDMA PA Power Management

The MAX77178/MAX77179 step-down converters are optimized for powering the power amplifier (PA) in multimode/multiband handsets for 3G/4G applications such as LTE, WCDMA, as well as other RF PA applications such as Wi-FiM and WiMAXM. The 2.5V to 5.5V input supply range supports both current and future battery chemistries. The MAX77179 uses an analog input dri.

Features
