DCS-Control ™Topology
down DC-DC converter optimized for applications
with high power density. A high switching frequency
of typically 2.5MHz allows the use of small inductors
and provides fast transient response as well as high
output voltage accuracy by utilization of the DCS-
Control™ topology.
Input Voltage Range: 4 to 17V
Up to 3A Output Current
Adjustable Output Voltage from 0.9 to 5V
Pin-Selectable Output Voltage (nominal, + 5%)
Programmable Soft Start and Tracking
Seamless Power Save Mode Transition
Quiescent Current of 19µA (typ.)
Selectable Operating Frequency
Power Good Output
With its wide operating input voltage range of 4V to
17V, the devices are ideally suited for systems
powered from either a Li-Ion or other batteries as well
as from 12V intermediate power rails. It supports up
to 3A continuous output current at output voltages
between 0.9V and 5V (with 100% duty cycle mode).
100% Duty Cycle Mode
The output voltage startup ramp is controlled by the
soft-start pin, which allows operation as either a
standalone power supply or in tracking configurations.
Power sequencing is also possible by configuring the
Enable and open-drain Power Good pins.
Short Circuit Protection
Over Temperature Protection
For Improved Feature Set, see TPS62130
Available in a 3 × 3 mm, QFN-16 Package
In Power Save Mode, the devices show quiescent
current of about 19μA from VIN. Power Save Mode,
entered automatically and seamlessly if 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 2μA.
