STMicroelectronics, ST1PS02D1QTR Sync Buck Converter Dual-Channel 400mA Selectable 12-Pin, TQFN

The STMicroelectronics ST1PS02 is a 400 mA Nano-quiescent, miniaturized 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).
