.. AS3665 1 General Description The AS3665 is a capacitive low noise charge pump with 9 current sources. The charge pump automatically switches between 1:1 and 1:1.5 modes. The connected current sources have a very low voltage pliance to improve efficiency of the whole system. Three current sources have the possibility to operate either from VBAT or VCP (especially useful for red LEDs). The internal control is done by mand based pattern generators implemented by three sequencers. These mands are optimized for lighting applications (e.g. ramp up brightness logarithmically). It includes high level mands like conditionals jumps and variables. Any of the three...
