TPS6213x 3V-17V 3A Step-Down Converter **General Description:** TPS6213x is an easy to use synchronous step down DC-DC converter optimized for applications wiht high power desity . A high switching frequency of typically 2.5MHz allows the use of small inductior and provides fast transient response as well as high output voltage accuracy by use to the DCS-Control Topology . With their wide operating input voltage range of 3V to 17V, the devices are ideally suited for systems powered from either a Li-Ion or other batteries as well as from 12V intermediate power rails. It supports up to 3A continuous output current at output voltages between 0.9V and 6V (with 100% duty cycle mode).The output voltage startup ramp is controlled by the soft-start pin, which allows operation as either a standalone power supply or in tracking configurations Power sequencing is also possible by configuring the Enable and open-drain Power Good pins. **Features** DCS-Control™ Topology Input Voltage Range: 3 to 17V Up to 3A Output Current Adjustable Output Voltage from 0.9 to 6V Pin-Selectable Output Voltage (nominal, + 5%) Programmable Soft Start and Tracking Seamless Power Save Mode Transition Quiescent Current of 17µA (typ.) Selectable Operating Frequency Power Good Output 100% Duty Cycle Mode Short Circuit Protection Over Temperature Protection
