The AST1S31 device is an internally compensated 1.5 MHz fixed-frequency PWM synchronous step-down regulator. The AST1S31 device operates from 2.8 V to 4 V input, while it regulates an output voltage as low as 0.8 V and up to VIN.
The AST1S31 integrates a 70 mΩ high-side switch and a 55 mΩ synchronous rectifier allowing very high efficiency with very low output voltages.
The peak current mode control with an internal compensation deliver a very compact solution with a minimum component count.
The AST1S31 device is available in a 3 x 3 mm, 8 leads VFDFPN package.
