Additional Infomation About Product

ST1S15 500 mA, 6 MHz synchronous step-down converter Datasheet - production data Description The ST1S15 is a high efficiency miniaturized step-down converter able to provide 500 mA output current from an input voltage from 2.3 V to 5.5 V. This converter is specifically designed for applications where high efficiency and small application area are the key factors. Thanks to Features 6 MHz switching frequency, the ST1S15 can use 470 nH nominal values for the inductor and 85% typical efficiency 4.7 F for the output capacitor providing, at the 500 mA output current capability same time, very good performance in terms of 45 A typical quiescent current load and line transients. A PFM mode can be PFM or PWM operation for best efficiency selected for high efficiency under light load over whole load range conditions or PWM mode for tight regulation and Ultra-fast load and line transient best dynamic performance. Short-circuit and Short-circuit and thermal protection thermal protection are also included.
