摘要: A LED drive circuit equipped with oscillator 18 , up/down counter 20 and DAC 22 in order to multiple LEDs 10 ( 1 )- m ) a block. Up/down carries out count-up/down operations sync clock CLK sent from during the ramping of pulse-lighting LEDs. converts count value DN into analog voltage signal V supplies it gate terminal NMOS transistor 14 via low-pass filter 28 buffer amplifier 24.
