STMicroelectronics STEVAL-1PS01EJR Evaluation Board

STMicroelectronics STEVAL-1PS01EJR Evaluation Board features an ST1PS01 nano-quiescent miniaturized synchronous step-down converter. The STMicroelectronics ST1PS01 converter is designed for applications where high efficiency, PCB size, and thickness are the key factors. The STEVAL-1PS01EJR evaluation board can provide up to 400mA output current with an input voltage ranging from 1.8V to 5.5V. Using two digital control inputs, the output voltage can be dynamically adjusted from 1.8V to 3.3V. The STEVAL-1PS01EJR evaluation board can achieve high-efficiency conversion using only a 2.2µH inductor and two small capacitors. This evaluation board incorporates advanced design circuitry that minimizes the quiescent current. The STEVAL-1PS01EJR evaluation board finds its applications in wearable devices, personal tracking monitors, and smartwatches.
