STEVAL-1PS02D

STEVAL-1PS02D is an evaluation board based on ST1PS02DQTR 400mA nano-quiescent synchronous step-down converter with AUX switch. The board embeds ST1PS02DQTR 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 same voltage rail. The board demonstrates how highly efficient conversion can be achieved using just ST1PS02DQTR, 2.2μH inductor, 2 small capacitors. The board highlights key application benefits of ST1PS02DQTR, 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, sport 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.
