TPS62152C-Q1数据手册TI中文资料规格书

描述 Description

The TPS62152C-Q1 device is an easy-to-use synchronous step-down DC-DC converter optimizedfor applications with high power density. A high switching frequency of typically 2.5 MHz allowsthe use of small inductors and provides fast transient response as well as high output-voltageaccuracy 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).
