Product overview
概要
The STEVAL-1PS03A is an evaluation board for 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 1.6 V to 3.3 V 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 2.2 μH 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, and is ideal for power conversion solutions in wearable applications and fitness accessories, personal tracking monitors, smart watches, sports bands, energy harvesting, wireless sensors, industrial sensors, portable low power devices, single cell Li-Ion battery applications and Bluetooth® low energy and Zigbee applications.
The device used on this board is supplied in the thin TQFN12 (2.0x1.7 mm) package.
