STMicroelectronics Evaluation Board Based on ST1PS02AQTR 400 mA Nano-Quiescent Synchronous Step-Down Converter with AUX

The STMicroelectronics STEVAL-1PS02A evaluation board allows evaluation of a smart converter design able to deliver up to 400 mA output current from a 1.8 V to 5.5 V input, with a dynamically adjustable 1.4 V to 1.75 V output voltage. The board embeds the ST1PS02AQTR nano-quiescent miniaturized synchronous step-down converter which 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.
