Low-power PWM only boost regulator for battery-powered applications

Fairchild's FAN48619 fixed-output synchronous TinyBoost regulator is now stocked by Mouser. The device is a low-power PWM only boost regulator designed to provide a minimum voltage-regulated rail from a standard single-cell Li-Ion battery and advanced battery chemistries. Even below the minimum system battery voltage, the device maintains the output voltage regulation for an output load current of 1000mA. The combination of built-in power transistors, synchronous rectification, and low supply current suit the FAN48619 for battery-powered applications. The FAN48619 is available in a 9-bump, 0.4mm pitch, (1.215mm x 1.215mm) wafer-level chip-scale package (WLCSP).
