NCP6354
3MHz, 2A Fixed-Frequency
Synchronous Buck
Converter
High Efficiency, Low Ripple, Adjustable
Output Voltage
The NCP6354, a synchronous buck converter, which is optimized to
supply the different sub systems of portable applications powered by
one cell Li−ion or three cell Alkaline/NiCd/NiMH batteries. The
device is able to deliver up to 2 A on an external adjustable voltage.
Operation with 3 MHz switching frequency allows employing small
size inductor and capacitors. Input supply voltage feedforward control
is employed to deal with wide input voltage range. Synchronous
rectification offers improved system efficiency. The NCP6354 is in a
space saving, low profile 2.0x2.0x0.75 mm WDFN−8 package.

PCB工艺的一些小原则
1: 印刷导线宽度选择依据: 印刷导线的最小宽度与流过导线的电流大小有关: 线宽太小,刚印刷导线电阻大,线上的电压降也就大,影响电路的性能, 线宽太宽,则布线密度不高,板面积增加,除了增加 ......
