STEVAL-1PS03A

STEVAL-1PS03A is an evaluation board for a smart converter design able to deliver up to 400mA output current from a 1.8V to 5.5V input with 1.6V to 3.3V dynamically adjustable output voltage. It features the ST1PS03AQTR nano-quiescent synchronous step-down converter with enhanced peak current control and embedded controlled load switch. 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 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, Bluetooth® low energy and Zigbee applications.
