TEXAS INSTRUMENTS TPS62150AQRGTTQ1 直流-直流开关降压(逐步递减)稳压器, 可调, 3V-17V输入, 900mV-6V输出, 1A输出, QFN-16
The TPS62150AQRGTTQ1 is an easy-to-use synchronous step-down DC-to-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 through the use of the DCS-Control™ topology. With a wide operating input-voltage range of 3 to 17V, 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 and 6V (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 17μA from VIN.
