效率85％的12v转5v降压转换器

标签：电源技术资料下载,
This application note describes how the NCP3063 can be configured as a buck controller to drive an external PFET transistor to produce a cost effective, high efficiency 3 A switching regulator. The NCP3063 has a wide input voltage range up to 40 V which makes it attractive for industrial and consumer applications such as LCD-TVs. The design example illustrates a buck converter delivering 3 A at 5 or 3.3 V from a 12 V supply.， 大小：498 KB
