CT21104

Li-Ion Battery Boost

CT21104 is high efficiency DCDC boost converter designed work with Li-Ion batteries. The boost converter is optimized for current load  up to 20mA and 3.3V to 15V selectable output voltage (2V of step). Regulation is performed fixed frequency voltage mode PWM technique. The CT21104 is designed to work with best efficiency in Discontinuous Conduction Mode (DCM).
