ST1PS02 Synchronous Step-Down Converter

STMicroelectronics ST1PS02 Synchronous Step-Down Converter provides up to 400mA output current with an input voltage ranging from 1.8V to 5.5V. This nano-quiescent step-down converter is specifically designed for applications where high efficiency, PCB size, and PCB thickness are the key factors. The output voltage can be set using two digital control inputs, a VOUT from 1.8V to 3.3V can be dynamically selected. Thanks to the enhanced peak current control PCC), the STMicroelectronics ST1PS02 reaches very high-efficiency conversion using a 2.2µH inductor and two small capacitors. This device embeds a controlled load switch to supply a subsystem with the same voltage rail. Advanced design circuitry is implemented to minimize the quiescent current.
