ST1S14PHR ST DC-DC Converters

The ST1S14PHR is a step-down monolithic power switching regulator from STMicroelectronics in HSOP-8 surface-mount package with exposed pad, featuring 3A DC output current and operating input voltage from 5.5V to 48V. For selection, verify adjustable output from 1.22V, 850kHz fixed switching frequency, internal soft-start, power good open collector output, current mode architecture, internal compensation network, zero load current operation, internal current limiting, inhibit pin for zero current consumption, 250mΩ typical RDS(on), and operating temperature from -40°C to +125°C. Features include thermal shutdown, pulse by pulse current limit, current foldback for persistent short circuit protection, and exposed pad for reduced thermal resistance (approximately 40°C/W). Ideal for factory automation, printers, DC-DC modules, high current LED drivers, distributed power systems, and any step-down DC-DC conversion requiring up to 3A output with wide input voltage range from 5.5V to 48V in compact HSOP-8 package.
