The TPS6209x devices are a family of high frequency synchronous step down converters optimized for small solution size, high efficiency and suitable for battery powered applications. To maximize efficiency, the converters operate in pulse width modulation (PWM) mode with a nominal switching frequency of 2.8 MHz/1.4 MHz and automatically enter power save mode operation at light load currents. When used in distributed power supplies and point of load regulation, the devices allow voltage tracking to other voltage rails and tolerate output capacitors ranging from 10 µF up to 150 µF and beyond. Using the DCS-Control™ topology the devices achieve excellent load transient performance and accurate output voltage regulation.

The output voltage start-up ramp is controlled by the softstart pin, which allows operation as either a standalone power supply or in tracking configurations. Power sequencing is also possible by configuring the enable and power good pins. In power save mode, the devices operate at typically 20 µA quiescent current. Power save mode is entered automatically and seamlessly maintaining high efficiency over the entire load current range.
