STMicroelectronics STEVAL-1PS02A Eval Board Based on ST1PS02AQTR

STMicroelectronics STEVAL-1PS02A Eval Board Based on ST1PS02AQTR is used to evaluate a smart converter design able to deliver up to 400mA output current. It features a 1.8V to 5.5V input, with a dynamically adjustable 1.4V to 1.75V output voltage. The board embeds the ST1PS02AQTR nano-quiescent miniaturized synchronous step-down converter. The converter implements enhanced peak current control (PCC) and advanced design circuitry to minimize quiescent current. It features a controlled load switch to supply a subsystem with the same voltage rail. The device is supplied in TQFN12 (2.0x1.7 mm) thin package, but other packages are also available. The board demonstrates how highly efficient conversion is achieved using just the ST1PS02AQTR, a 2.2μH inductor, and two small capacitors.
