STEVAL-1PS02A

STEVAL-1PS02A is an evaluation board based on ST1PS02AQTR 400mA nano-quiescent synchronous step-down converter with AUX switch. 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 subsystem with same voltage rail. The board demonstrates how highly efficient conversion can be achieved using just ST1PS02AQTR, 2.2μH inductor and 2 small capacitors. The board highlights ST1PS02AQTR key application benefits, including high efficiency and small PCB size and thickness and is ideal for power conversion solutions in wearable applications, 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 as well as Bluetooth® low energy and Zigbee applications.
