STPMS1BPQR ST Power Management IC | 16-QFN（3X3） | 2.5V-5.5V, 1.5A

Product Overview

The STPMS1BPQR is a high-performance power management IC from STMicroelectronics, designed for compact and efficient power conversion in space-constrained applications. Housed in a 16-QFN (3x3 mm) package, it integrates a step-down DC-DC converter with a maximum output current of 1.5A. The device operates over a wide input voltage range from 2.5V to 5.5V, making it suitable for battery-powered and low-voltage systems. Its high switching frequency (up to 2 MHz) allows for small external components, reducing overall solution size.
