TLV62130ARGTT
TEXAS INSTRUMENTS TLV62130ARGTT 直流-直流开关降压逐步递减稳压器, 可调, 4V-17V输入, 900mV-5V输出, 3A输出, QFN-16
The 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 by use of the DCS-Control™ topology. With their wide operating input voltage range of 3 to 17V, the device is ideally suited for systems powered from either a Li-ion or other batteries as well as from 12V intermediate power rails. It supports up to 3A continuous output current at output voltage from 0.9 to 5V 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 draws quiescent current of about 19µA from VIN.
