TI TPS84620RUQ 6A电源解决方案

TI 公司的TPS84620RUQ是容易使用的 6A DC/DC转换器,并在小型BQFN封装莻集成了功率MOSFET,电感和无源元件,只需要3个外接元件就形成整体电源解决方案.效率高达96%, 输入电压可低至1.7V,输出电压从1.2V到5.5V,可调开关频率(480kHz 到780 kHz),主要用在宽带和通信基础设备以及自动测试和医疗设备.本文介绍了TPS84620RUQ主要特性,功能方框图,多种应用电路图以及TPS84620EVM-692 6-A评估板主要特性,电路图和材料清单(BOM).

The TPS84620RUQ is an easy-to-use integrated power solution that combines a 6-A DC/DC converter with power MOSFETs, an inductor, and passives into a low profile, BQFN package. This total power solution allows as few as 3 external components and eliminates the loop compensation and magnetics part selection process.

The 9×15×2.8 mm BQFN package is easy to solder onto a printed circuit board and allows a compact point-of-load design with greater than 90% efficiency and excellent power dissipation with a thermal impedance of 13°C/W junction to ambient. The device delivers the full 6-A rated output current at 85°C ambient temperature without airflow.

The TPS84620 offers the flexibility and the feature-set of a discrete point-of-load design and is ideal for powering performance DSPs and FPGAs
