MAX8627 Description
The MAX8627 step-up converter is a high-efficiency, low-quiescent current, synchronous boost converter with True Shutdown™ and inrush current limiting. The MAX8627 generates any boosted output voltage from 3V to 5V from either a 2-cell NiMH/NiCd or a single-cell Li+/Li polymer battery. Quiescent current is only 20µA (typ), and at light loads the converter pulses only as needed for best efficiency.
