The ST1S31 device is an internally compensated 1.5 MHz fixed-frequency PWM synchronous stepdown regulator. The ST1S31 operates from 2.8 V to 5.5 V input, while it regulates an output voltage as low as 0.8 V and up to VIN. The ST1S31 integrates a 60 mΩ high-side switch and a 45 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 ST1S31 device is available in 3 mm x 3 mm, 8 lead VFDFPN and SO8 packages.
