product description

The RM9006A is an LED constant current driver chip that can adjust the brightness/color temperature in stages.

The RM9006A is suitable for 220VAC or 120VAC input voltage with constant current accuracy of ±3%.

In the segment adjustment brightness application, the RM9006A can change the brightness of the LED lamp in turn according to the power switch on and off. The adjustment ratio can be adjusted by an external resistor.

RM9006A can adjust the color temperature application according to the turn-on and turn off the power switch, and change the switch state of the two output ports in turn to realize the alternate lighting of two different color LED lights to achieve the purpose of adjusting the color temperature. Adjust the external REXT resistor to output. Power is adjusted.

The RM9006A is available in an ESOP8 package.
