Product introduction

CYT1003AEG is a single-channel high-voltage linear constant current LED drive 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 an input PWM pin voltage. The PWM waveform can be converted to a dimming voltage by a simple filter circuit.

CYT1003AEG can realize the LED light string fully tumed off. When the PWM port input is connected to GND, the CYT1003AEG completely turns off the internal LDNMOS.and the current on the LED string is zero.
