TPS62130ARGTR

The TPS6213x family are easy-to-use synchronous
step down DC-DC converters optimized for
applications with high power density. A high switching
frequency of typically 2.5 MHz allows the use of small
inductors and provides fast transient response as well
as high output voltage accuracy by use of the DCSControl topology.
With their wide operating input voltage range of 3 V
to 17 V, the devices are ideally suited for systems
powered from either a Li-Ion or other batteries as
well as from 12-V intermediate power rails. They
support up to 3-A continuous output current at output
voltages between 0.9 V and 6 V (with 100% duty
cycle mode). The output voltage start-up ramp is
controlled by the soft-start pin, which allows operation
as either a stand-alone power supply or in tracking
configurations. Power sequencing is also possible by
configuring the Enable and open-drain Power Good
pins.
In power save mode, the devices draw quiescent
current of approximately 17 μA from VIN. Power save
mode, entered automatically and seamlessly if the
load is small, maintains high efficiency over the entire
load range. In shutdown mode, the device is turned
off and shutdown current consumption is less than 2
μA.
The device, available in adjustable and fixed output
voltage versions, is packaged in a 16-pin VQFN
package measuring 3 mm × 3 mm (RGT).
