The ST1S15 is a high efficiency miniaturized step-down converter able to provide 500 mA output current from an input voltage from 2.3 to 5.5. This converter is specifically designed for applications where high efficiency and small application area are the key factors. With an output voltage as low as 0.6 V the device supports low voltage DSPs and processors core supply. Due to the 6 MHz switching frequency the ST1S15 can use nominal values of 470 nH for the inductor and 4.7 µF for the output capacitor, providing, at the same time, very good performance in terms of load and line transients. It is possible to select a PFM mode for high efficiency under light load conditions or PWM mode for tight regulation and best dynamic performance. Short-circuit and thermal protection are included.
