LTC3202 is an electric charge pump without gates which is produced by Linear Technology Corp., in the figure is the Li-ion battery drive white light LED circuit composed of LT3202 electric charge pump. To solve the problem of noise, LTC3202 is equipped with linear regulation technology, which can make sure the converting capacitance charge and discharge volume meet the need of the loading current, and it can keep it at the constant volume in each period, so they won't generate the audio weight.
