TPS62171DSGT

3-17V 0.5A降压转换器与DCS- ControlTM 3-17V 0.5A Step-Down Converter with DCS-ControlTM

DESCRIPON

The TPS6217X family is an easy to use synchronous step down DC-DC converter optimized for

applications with high power density. A high switching frequency of typically 2.25MHz 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, the devices are ideally suited for systems powered from either a Li-Ion or other battery as well as from 12V intermediate power rails. It supports up to 0.5A continuous output current at output voltages between 0.9V and 6V with 100% duty cycle mode.
