Low VBATT, 20µA IQ, 1MHz Synchronous Boost Converter with True Shutdown
General 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. At higher loads, PWM mode maintains fixed 1MHz operation for lowest noise and ripple. The MAX8627 includes an internal soft-start...
