STEVAL-1PS03A

STEVAL-1PS03A is an evaluation board 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 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. The board highlights key application benefits made possible by the ST1PS03AQTR, including high efficiency and small PCB size and thickness.
