MAX1686 Features

* o Low 450mA Peak Battery Current Provides 2A, 5V GSM Burst o 90% Efficiency o Internal Power MOSFETs and Current-Sense Resistor o Output Disconnects from Input During Shutdown o 3µA Shutdown Current o Precise Voltage-Controlled Current Limit (MAX1687) o Adaptive Constant-Recharge-Time Capability (MA

MAX1686 Applications

* such as GSM cell phones and wireless LANs, where the RF power amplifiers require short, high current bursts. The MAX1687/MAX1688 reduce battery surge current by slowly charging a reservoir capacitor, which supplies the necessary peak energy for the load current burst. As a result, the peak battery c
