Step-down converters designed for high efficiency

They are available at distributor Anglia Components.

The devices are able to provide up to 400 mA output current with an input voltage ranging from 1.8 V to 5.5 V.

This converter series has been specifically designed for applications where high efficiency, PCB size and thickness are critical factors such as battery-powered and energy-harvesting applications, as it ensures a highly efficient conversion regardless of the power source.

The ST1PS01 / ST1PS02 / ST1PS03 miniaturised step-down regulators draw a quiescent current of just 500 nA.

This new generation of buck converters requires a minimal set of external components thanks to the integrated power switch, synchronous rectifier, and integrated compensation network.

The high efficiency and small PCB size and thickness requirement for the ST1PS01 / ST1PS02 / ST1PS03 devices make them 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 application
