STMicroelectronics STEVAL-1PS03A Converter Evaluation Board

 

STMicroelectronics STEVAL-1PS03A Converter Evaluation Board is for a smart converter design able to deliver up to 400mA output current from a 1.8V to 5.5V input, with a dynamically adjustable 1.6V to 3.3V output voltage. The board features the ST1PS03AQTR nano-quiescent miniaturized synchronous step-down converter, which implements enhanced peak current control (PCC) and advanced design circuitry to minimize quiescent current. The device embeds a controlled load switch to supply a subsystem with a VIN_AUX voltage rail. The board demonstrates how highly efficient conversion can be achieved with just the ST1PS03AQTR, a 2.2μH inductor, and two small capacitors.
