The TPS6213X series is an easy-to-use synchronous step-down DC-DC converter for high power density applications. The high switching frequency of typically 2.5MHz allows the use of small inductors and provides fast transient response and high output voltage accuracy through the DCSControl™ topology.

Due to its wide operating input voltage range of 3V to 17V, the device is ideal for systems powered by Li-Ion or other batteries, as well as from a 12V intermediate supply rail. It supports up to 3A continuous output current between output voltages of 0.9V to 6V (100% duty cycle mode). The output voltage start-up ramp is controlled by a soft-start pin, which allows operation as a standalone supply or in a tracking configuration. Power sequencing can also be achieved by configuring the enable and open-drain power-good pins.

In power saving mode, the device draws a quiescent current of about 17µA VIN. Power saving mode, automatic and seamless input, maintains high efficiency over the entire load range if the load is small. In shutdown mode, the device is turned off and the current consumption is less than 2μA. Available in adjustable and fixed output voltage versions, the device is packaged in a 16-pin VQFN package measuring 3 x 3mm (RGT).
