Texas Instruments TPS6215x 3-17V 1A Step-Down Converters

Texas Instruments TPS6215x 3-17V 1A Step-Down Converters are easy-to-use synchronous step down DC-DC converters optimized for applications with high power density. A high switching frequency of typically 2.5MHz allows the use of small inductors and provides fast transient response as well as high output voltage accuracy by utilization of the DCS-Control™ topology. With its wide operating input voltage range of 3V to 17V, these TI devices are ideally suited for systems powered from either a Li-Ion or other batteries as well as from 12V intermediate power rails. These step-down converters support up to 1A continuous output current at output voltages between 0.9V and 6V (with 100% duty cycle mode).
