Product overview

RM9006A is a segmented adjustable brightness / color temperature LED constant current drive chip.

RM9006A applies to 220V AC or 120V AC input voltage, constant current accuracy of + 3%.

RM9006A in the application of brightness adjustment, according to open and close the power switch, in turn to change the brightness of the LED lamp, adjust the ratio can be adjusted by external resistance.

RM9006A in the regulation of color application, according to open and close the power switch, which in turn two output ports switch state, alternating light to achieve the purpose of regulating the color temperature of two different color LED light, adjusting the external REXT resistance on output power adjustment.

RM9006A uses ESOP8 package.

Functional characteristics

1, the external circuit is simple, no magnetic components;

2, multi chip series or parallel applications;

3, the chip can be shared with the PCB board LED;

4, constant current accuracy + 3%;

5, built-in over temperature compensation (over temperature adjustment node: 125 degrees C);

6, the subsection brightness, the proportion can be set externally;

7, built-in 600V high voltage MOS;

8, 3 seconds switch switch light / color;
