Description

The ST1S40 is an internally compensated 850 kHz fixed-frequency PWM synchronous step-down regulator. ST1S40 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 ST1S40 integrates a 95 mΩ high side switch and 69 mΩ synchronous rectifier allowing...
