  • introduction

    MC1051 is a LED linear constant-current driver chip, the current output range from 3 to 2500mA, the current value through the external resistance can constitute a complete LED constant-current driver circuit.The operating voltage range of the chip is 2.5~6V. 

      MC1051 built-in overheating protection function to avoid damage caused by overheating.

      MC1051 has PWM dimming function. The LED current can be adjusted by adding PWM signal at DIM foot.
