TPS62150A-Q1, TPS62153A-Q1
SLVSCC3 –MAY 2014
TPS6215xA-Q1 3V to 17-V 1A Step-Down Converter with DCS-ControlTM
1 Features
3 Description
The TPS62150A-Q1 device is an easy-to-use
synchronous step-down DC-DC converter 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
through the use of the DCS-Control™ topology.

With a wide operating input-voltage range of 3 to 17
V, the device is ideally suited for systems powered
from intermediate bus power rails. The device
supports up to 1A continuous output current at output
voltages between 0.9 V and 6 V (with 100% duty
cycle mode).

Input Voltage Range: 3 to 17V
Adjustable Output Voltage from 0.9 to 6V
Pin-Selectable Output Voltage (nominal, + 5%)
Programmable Soft Start and Tracking
Seamless Power Save Mode Transition
Quiescent Current of 17µA (typ.)
Power Good Output
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.
100% Duty Cycle Mode
Short Circuit Protection
In power save mode, the device shows quiescent
current of about 17 μA from VIN. Power save mode
which is 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 is packaged in a 16-pin VQFN
package measuring 3 × 3 mm (RGT).
