适用于汽车音频应用的双相同步降压转换器参考设计

PMP20440 is a dual phase synchronous buck converter reference design for 12V output at 11A from an input voltage of 6V to 17V. At an input voltage of 12V or less the output will follow with a small voltage drop. This design uses the LM5140-Q1 dual phase synchronous buck controller at a free-running switching frequency of 440 kHz. Features include external frequency synchronization, enable and power good.
