MAX77179 High-Bandwidth LTE/WCDMA PA Power Management

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 futur.

Features

include overcurrent and overtemperature protection, and a very low-current (0.1µA, typ) shutdown mode. WiMAX is a registered certification mark and service mark of WiMAX Forum. Wi-Fi is a registered certification mark of Wi-Fi Alliance Corporation. Features S Meet 3G/4G Timing and RF Spectrum Mask Requirements
