Part Description

The TPS6217x device family are easy to use synchronous step-down DC-DC converters optimized for applications with high power density. A high switching frequency of typically 2.25 MHz 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 3 V to 17 V, the devices are ideally suited for systems powered from either a Li-Ion or other battery as well as from 12-V intermediate power rails. It supports up to 0.5-A continuous output current at output voltages between 0.9 V and 6 V (with 100% duty cycle mode). Power sequencing is also possible by configuring the enable and open-drain power good pins. In power save mode, the devices show quiescent current of about 17 μA from VIN. Power save mode, entered automatically and seamlessly if the load is small, maintains high efficiency over the entire load range. In shutdown mode, the device is turned off and shutdown current consumption is less than 2 μA. The TPS6217x devices operate over a free air temperature range of –40°C to 85°C. They are available in adjustable and fixed output voltage versions. The devices are packaged in a 2-mm × 2mm 8-pin WSON package (DSG).
