The ST1PS01 is a nano-quiescent miniaturized synchronous step-down converter, which is able to provide up to 400 mA output current with an input voltage ranging from 1.8 V to 5.5 V. This converter is specifically designed for applications where high efficiency, PCB size and thickness are the key factors. The output voltage can be set using two digital control inputs, a VOUT from 1.8 V to 3.3 V can be dynamically selected. Thanks to the enhanced PCC (peak current control) the ST1PS01 reaches very high efficiency conversion using just a 2.2 µH inductor and two small capacitors. Advanced design circuitry is implemented to minimize the quiescent current. The device is available in Flip-Chip package.
