Introducing the STMicroelectronics ST1PS01 / ST1PS02 / ST1PS03 nano-quiescent synchronous step-down converters, samples and evaluation boards available from Anglia

The ST1PS01 / ST1PS02 / ST1PS03 devices from STMicroelectronics are a family of nano-quiescent miniaturized synchronous step-down converters. 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 miniaturized 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.

See below overview of the ST1PS01 / ST1PS02 / ST1PS03 devices:

ST1PS01 – Featuring an output voltage that can be set using two digital control inputs, a VOUT from 0.625 V to 3.3 V can be dynamically selected.
