RT8279 DEMO板，Pads9.5绘制，包含原理图和PCB文件。 做板验证过，短时间5A没问题，如果长时间5A工作，板子需要额外增加散热片。 板层2层。大面积敷铜。默认输出5V，可以更换FB管脚对应的两颗电阻值改变输出电压大小。

The RT8279 is a step-down regulator with an internal power MOSFET. It achieves 5A of continuous output current over a wide input supply range with excellent load and line regulation. Current mode operation provides fast transient response and eases
