Product Summary

The MAX1686HEUA is a step-up DC-DC converter delivers up to 2W from a single Li-Ion or three NiMH cells. The device is ideal for burst-load applications such as GSM cell phones and wireless LANs, where the RF power amplifiers require short, high current bursts. The MAX1686HEUA reduces battery surge current by slowly charging a reservoir capacitor, which supplies the necessary peak energy for the load current burst. The applications of the MAX1686HEUA include GSM Phones, Wireless Handsets, PC Cards (PCMCIA).
