The RCD-24-xxx/PL series is a step-down constant current source designed for driving high power LEDs.

The converter uses a pinless SMD open frame design to reduce cost and size. Output currents available are 300mA, 350mA, 500mA, 600mA, 700mA and 1000mA with either Class A (Suffix /A) or Class B (suffix /B) built-in EMC filtering. Despite its compact size, the RCD-PL series is fully featured with very high efficiency, wide input voltage range, high ambient operating temperature and two means of LED dimming: PWM/digital control and analogue voltage dimming. Both 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 ambient operating temperature and is designed for strip lighting, wall washers and flourescent tube replacement designs, where a low profile and narrow width are demanded.

    The PWM-control pin can be used as remote control pin as well. It means you can switch the unit on/off via this pin. Switching level is TTL compatible and has hysteresis to allow slow switching waveforms.
    Yes, our RACVxx series offer constant voltage outputs. The difference between a lighting CV driver and an industrial CV power supply is that the RACV's have full LED lighting certifications. (note: industial power supplies need PFC only above 75W. LED lighting regulations specify PFC from 25W. It is not permitted to use non-PFC power supplies above 25W)
    Yes, for our AC input drivers we offer 0-10V analog dimming, TRIAC dimming and Thermal dimming.
    The analog voltage is used to control an internal PWM circuit.
    The controller chip has a multi-stage shutdown:
    On : Open or 0V < Vr < 0.6V
    minimum quiescent current - all circuits shut down - slowest restart response time
    Off (Standby) : 0.6V < Vr < 2.9V
    output power stage and PWM oscillator off - medium restart response time
    Off (Shutdown) : 2.9V < Vr < 6V
    output power stage off, all other circuits active - quickest restart response time
    The RCD-24 series is step-down (buck) converter. You always need a higher input voltage than the output voltage required. A high power LED usually has a forward voltage drop of around 3.4V, so only three LEDs can be drivenin series from a 12V source. If the input voltage is increased to 24V, seven LEDs can be in the chain and if the input voltage is 36V, then ten LEDs can be driven.
    However, it is possible to connect chains of LEDs in parallel, so a RCD-24-7.0 can drive two chains of three 350mA LEDs connected in parallel.
    Remember that this part is a constant current converter, so the output voltage is variable depending on the power needed, but it will always be lower than the input voltage.
    The RCD series is a All-in-One solution in a small package with high efficiency, wide input range, two different ways of dimming Analog and Digital (PWM), high operating temperature range, and it’s fully tested. You don’t have to worry about all different suppliers of all the components of your discrete solution.
    The linearity outside the 10~90% range of the PWM dimming is not perfect, but still pretty good. The Analog dimming can be used in a 0~100% range.
