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.
