STMICROELECTRONICS ST1PS01HJR Nano Buck Converter

The ST1PS01 is a nano-quiescent, ultra-low power buck converter designed for compact, high-efficiency power management in wearable, portable, and industrial low-power devices. It delivers up to 400 mA current with input voltages from 1.8 V to 5.5 V, featuring dynamic output voltage adjustment, seamless transition between PFM and PWM modes, and a tiny Flip-Chip package. Ideal for energy harvesting, Bluetooth low energy, and Zigbee applications, it minimizes quiescent current to just 500 nA for optimized battery life in space-constrained designs.
