3 Description
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.
