Description
The RCD series is a step-down constant current source designed for driving high power white LEDs. The standard
output current is 700mA. Despite its compact size, the RCD series is fully featured with very high efficiency, wide input
voltage range, high ambient operating temperature and three means of LED dimming: PWM/digital control, analogue
voltage and potentiometer dimming. All dimming controls are independent and can be combined. The driver is also
designed to be as reliable as the LEDs it is driving, even at the full operating temperature of 85°C. An SMD version is
also available.

Specifications
( typical at 25°C, nominal input voltage, rated output current unless otherwise specified )
IMPORTANT INFORMATION: The RCD-24B-0.70/SMD series are not suitable to be soldered using vapour
phase soldering, they are only guaranteed to be safe in IR or convection reflow ovens and by hand
soldering. Reflow conditions should not exceed the limits of the Jedec STD-020C profile. This restriction
applies to the product series R-78Ax.x-0.5SMD, R-78Ax.x-1.0SMD and RCD-24B-0.70/SMD only and
does not affect any other RECOM products. For more details regarding this matter please contact
