EVAL BOARD , SYNC BUCK CONVERTER

Evaluation board based on ST1PS01AJR 400mA nano-quiescent synchronous step-down converter. This evaluation board features the ST1PS01 miniaturized, nano quiescent, synchronous step-down converter designed for applications where high efficiency, PCB size and thickness are the key factors. The converter can provide up to 400mA output current with a 1.8V to 5.5V input voltage range. The output voltage can be dynamically adjusted from 1.9V to 2.8V using two digital control inputs. Thanks to the enhanced peak current control (PCC), the ST1PS01 can achieve very high efficiency conversion using only a 2.2µH inductor and two small capacitors. Typical applications include wearable applications, personal tracking monitor, smart watches, sport bands, energy harvesting, wireless sensors, wearable and fitness accessories, industrial sensors, portable low power devices, single cell Li-Ion battery applications, Bluetooth® low energy and Zigbee.

• Up to 400mA output current capability
• Tiny external components (L=2.2µH typ)
• Output voltage power good
• Dynamic output voltage selection (D0, D1)
• Converter's advanced design circuitry reduces quiescent current to a minimum
