TLD6098-1EP和TLD6098-2ES内嵌PWM生成器,便于实现调光功能。 生成的PWM信号占空比是DC/PWMI引脚上模拟电压的函数。 联系DC/PWMI电压和生成占空比(DC)的方程式提取于通过两点的直线: (x - x1) / (x2 - x1) = (y - y1) / (y2 - y1) 其中:x1 = VDC(0%), y1 = 0% and x2 = VDC(100%), y2 = 100%, DC是VDC/PWMI电压的函数,方程式为: DC = 100 / (VDC(100%) - VDC(0%)) * (VDC / PWMI - 1) 就规格书典型值而言,即: DC = 38.46 * VDC / PWMI - 38.46

根据引脚电压,反馈给芯片内部的PWM发生器,产生对应的PWM占空比,影响MOS的ON/.OFF,实现调光
