EVALUATION KIT AVAILABLE MAX77178 / MAX77179 High-Bandwidth LTE/WCDMA PA Power Management ICs in a 1.75mm x 1.4mm, 0.4mm Pitch WLP General Description 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 driven by an external DAC to control the output voltage linearly for continuous PA power adjustment. The output voltage range (0.5V to VIN) supports operation with a wide variety of PAs.
