Product Description

The ST1S50PUR is a monolithic synchronous step-down Switching Converter with high efficiency at light load. The synchronous step-down regulator operates from 4 to 18V input, while it regulates an output voltage as low as 0.8V and up to 0.88 x VIN. The ST1S50 device integrates a 95mR high-side switch and a 69mR synchronous rectifier allowing very high efficiency with very low output voltages. The peak current-mode control with a special PFM mode enables high efficiency at a light load.
