Step-Down DC/DC Converters Integrated Switch 9V to 30V Input Max., Texas Instruments### 直流/直流开关调节器转换器(集成开关),Texas InstrumentsTexas Instruments 的此系列高度集成的高效开关稳压器包括步升(升压)、步降(降压)、步升/降(增压/降压)和反相类型,为每个直流稳压器应用提供高效的解决方案。
The TPS6215x family 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 by the use of DCS-Control topology.
With their wide operating input-voltage range of 3 V to 17 V, the devices are ideally suited for systems powered from either Li-Ion or other batteries as well as from 12-V intermediate power rails. The devices support up to 1-A continuous output current at output voltages between 0.9 V and 6 V in 100% duty-cycle mode. The soft-start pin controls the output-voltage start-up ramp, which allows operation as either a standalone power supply or in tracking configurations. Power sequencing is also possible by configuring the enable EN and open-drain power-good PG pins.
In power-save mode, the devices draw quiescent current of about 17 µA from VIN. Power-save-mode, entered automatically and seamlessly if the load is small, maintains high efficiency over the entire load range. In shutdown mode, the device turns off and current consumption is less than 2 µA.
The device, available in adjustable- and fixed-output-voltage versions, comes in a 16-pin VQFN package measuring 3 × 3 mm RGT.
