STMicroelectronics STEVAL-1PS02B Evaluation Board demonstrates a smart converter design able to deliver up to 400mA output current from a 1.8V to 5.5V input, with a dynamically adjustable 1.8V to 2.5V output voltage. The Evaluation Board features the ST1PS02BQTR nano-quiescent miniaturized synchronous step-down converter, which implements enhanced Peak Current Control (PCC) and advanced design circuitry to minimize quiescent current (IQ). The device embeds a controlled load switch to supply a subsystem with the same voltage rail. The Evaluation Board demonstrates how highly efficient conversion can be achieved with just the ST1PS02BQTR, a 2.2µH inductor, and two small capacitors.
The STEVAL-1PS02B Evaluation Board highlights key application benefits made possible by the ST1PS02BQTR, including high efficiency and small PCB size and thickness, and is ideal for power management solutions in wearable applications and fitness accessories, single-cell Li-Ion battery applications, and Bluetooth® low energy and Zigbee applications.
The pre-mounted ST1PS02BQTR is supplied in the thin TQFN12 (2.0mm x 1.7mm) package, ideal for space-constrained applications.
