Charge Pump Efficiency The AAT3111 is a regulated output voltage dou- bling charge pump. The efficiency ( ) can simply be defined as a linear voltage regulator with an effective output voltage that is equal to two times the input ...
Page 12
There are several methods that can be employed to reduce output ripple depending upon the require- ments of a given application. The most simple and straightforward technique is to increase the value of the C capacitor. The nominal 10µF C ...
