Product Summary

The MAX8815A DC-DC step-up converter is a high-efficiency,
low quiescent current, synchronous step-up
converter with True Shutdown? and inrush-current limiting.
The MAX8815A generates any output voltage
from 3.3V to 5V from a 2-cell NiMH/NiCd or a single-cell
Li+/Li polymer battery.
