CYT1003AG 雙通道高壓線性恒流LED驅(qū)動芯片PWM調(diào)光功能
CYT1003AG is a dual-channel high-voltage linear constant current LED driver chip with dimming function. It
adopts linear constant current technology to set the maximum driving current of LED string through external resistor. The output drive current can be adjusted by external input PWM pin voltage. The PWM waveform can be converted to a dimming voltage by a simple filter circuit. CYT1003AG can result the LED light string fully turned off.
When the PWM port input is connected to GND, CYT1003AG completely turns off the internal LDNMOS, the current on the LED string is zero.
