摘要
阐述高PF去频闪的芯片BL8392,能够适用于各类隔离、非隔离高PF的芯片。该芯片采用专利的VDD供电电路,外围不需要VDD电容,芯片采用自适应去纹波的方式,可以实现10%左右的纹波电流效果,以及手机拍摄无频闪。
This paper describes the BL8392 chip with high PF flicker reduction,which can be applied to various isolated and non isolated high PF chips.The chip adopts a patented VDD power supply circuit,without the need for VDD capacitors on the periphery.The chip adopts an adaptive ripple removal method,which can achieve a ripple current effect of about 10%,and there is no flicker phenomenon in mobile phone shooting.
