MAX8896 Datasheet Dual Pwm Step-down Converter

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-4663; Rev 0; 5/09 .. Dual PWM Step-Down Converter in a 2mm x 2mm Package for WCDMA PA and RF.

General Description

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.

Key Features

  • include separate output enables, lowsupply current shutdown, output overcurrent, and overtemperature protection. The MAX8896 is available in a 16-bump, 2mm x 2mm UCSP™ package (0.7mm max height). Features o PA Step-Down Converter (OUT1) 7.5µs (typ) Settling Time for 0.5V to 1V Output Voltage Change Dynamic Output Voltage Setting from 0.5V to VBATT 140mΩ Bypass PFET and 100% Duty Cycle for Low Dropout 2MHz Switching Frequency Low Output Voltage Ripple 700mA (min) Output Drive Capability 2% Gain.
