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™
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).
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.
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).
