MAX77178 Datasheet High-bandwidth Lte/wcdma Pa Power Management

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: EVALUATION KIT AVAILABLE MAX77178 / MAX77179 High-Bandwidth LTE/WCDMA PA Power Management ICs in a 1.75mm x 1.4mm, 0.

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.

Key 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.
  • 20µs (typ) Settling Time for 0.5V to 3.4V Output Voltage Change.
  • 30µs (typ) Settling from Enable to 95% Output Voltage Regulation S Four Selectable Output Voltages with Logic.
