製品概要

概要

The ST1S50 device is a 500 kHz fixed frequency PWM synchronous step-down regulator. The ST1S50 operates from 4.0 V to 18 V input, while it regulates an output voltage as low as 0.8 V and up to 0.88 x VIN.

The ST1S50 device integrates a 95 mΩ high-side switch and a 69 mΩ 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.

The ST1S50 device is available in a VFDFPN10 3 x 3 x 1 mm - 10 leads package.
