ST1S50PUR ST DC-DC Converter | 10-VFDFPN（3x3） | 4A Output, 4.5-18V Input

Product Overview

The ST1S50PUR is a high-efficiency, monolithic synchronous step-down DC-DC converter from STMicroelectronics. It is designed to deliver up to 4A of continuous output current over a wide input voltage range from 4.5V to 18V. The device integrates low RDS(on) power switches, which minimizes external component count and simplifies PCB layout. The ST1S50PUR is housed in a compact 10-VFDFPN (3x3 mm) package, making it ideal for space-constrained applications. With its high switching frequency (up to 1.5 MHz), the converter enables the use of small inductors and capacitors, further reducing the overall solution footprint. The device features a fixed 3.3V output voltage option, but can be adjusted externally via a resistor divider. Protection features include overcurrent protection, thermal shutdown, and undervoltage lockout.
