Typical Application for ST1S41 4 A step-down switching regulator
Progetto di riferimento di: STMicroelectronics
Typical Application for the ST1S41 is an internally compensated 850 kHz fixed-frequency PWM synchronous stepdown regulator. The ST1S41 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 ST1S41 integrates 95 m ohm high-side switch and 69 m ohm synchronous rectifier allowing very high efficiency with very low output voltages
