The STMicroelectronics ST1PS01 is a 400 mA Nano-quiescent synchronous step-down converter with digital voltage selection and power. The converter is specifically designed for applications where high efficiency, PCB size and thickness are the key factors. Advanced design circuitry is implemented in order to minimize the quiescent current. The ST1PS01 reaches very high efficiency conversion using just a 2.2 μH inductor and two small capacitors, due to the enhanced PCC (peak current control).
