ST ST1S41PHR

降压降压4V18V4A

Overview

The ST1S41PHR is an internally compensated 850 kHz fixed-frequency PWM synchronous step-down regulator. The ST1S41PHR operates from 4.0 V to 18 V input, while it regulates an output voltage as low as 0.8 V and up to VIN.

The ST1S41PHR integrates 95 mΩ high-side switch and 69 mΩ synchronous rectifier allowing very high efficiency with very low output voltages. The peak current mode control with internal compensation delivers a very compact solution with a minimum component count. The ST1S41PHR is available in VFQFPN 4 mm x 4 mm 8-lead package and HSOP-8.
