在干擾背景光下也有較少的探測錯誤

該光調(diào)制型光IC適合在背景干擾光下進(jìn)行光同步探測。光電二極管、前置放大器、比較器、振蕩器、LED驅(qū)動和信號處理電路都被集成在一個整體光IC芯片上。通過把外置LED連接到該IC上，可以簡單地配置出不易受干擾背景光干擾的光同步型光反射器和光斬波器。 \n- 允許的背景光亮度級大，典型值為3000 lx?\n- 最小探測量：典型值?0.2 uW/mm2\n- 數(shù)字輸出（光入射時輸出L）;

Highly Integrated Green-Mode PWM Controller

Description The SG6846A is especially designed for SMPS with surge-current output, incorporated with a two-level OCP function. Besides the cycle-by-cycle current limiting, if the switching current is higher than two thirds the peak current threshold for 1700ms, over-current protection is act
