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.
