MAX1688 - Step-Up DC-DC Converters

This page provides the datasheet information for the MAX1688, a member of the MAX1687 Step-Up DC-DC Converters family.

Description

The MAX1687/MAX1688 step-up DC-DC converters deliver up to 2W from a single Li-Ion or three NiMH cells.

The devices are ideal for burst-load applications such as GSM cell phones and wireless LANs, where the RF power amplifiers require short, high current bursts.

19-1426; Rev 0; 2/99 EVFAOLLULAOTWIOSNDKAITTAMSAHNEUEATL Step-Up DC-DC Converters with Precise, Adaptive Current Limit for GSM MAX1687 /MAX1688† General Description The MAX1687/MAX1688 step-up DC-DC converters deliver up to 2W from a single Li-Ion or three NiMH cells. The devices are ideal for burst-load 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 current is limited, thus maximizing battery life and minimizing battery voltage sag and transient dips.
