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 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 ST1S40 is available in VFQFPN 4 mm x 4 mm 8 lead package, HSOP-8 and standard SO-8 package.
