Description

The TPS62150A-Q1 device is an easy-to-use synchronousstep-down DC-DC converter optimized for applications with high power density. A high switchingfrequency of typically 2.5 MHz allows the use of small inductors and provides fast transientresponse 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 forsystems powered from intermediate bus power rails. The device supports up to 1A continuous outputcurrent 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 allowsoperation as either a standalone power supply or in tracking configurations. Power sequencing isalso possible by configuring the enable and open-drain power-good pins.

In power save mode, the device shows quiescent current of about 17 μA fromVIN. Power save mode which is entered automatically and seamlessly if theload is small, maintains high efficiency over the entire load range. In shutdown mode, the deviceis turned off and shutdown current consumption is less than 2 μA. The device is packaged in a16-pin VQFN package measuring 3 × 3 mm (RGT).
