Current Is the Driving Force: The New RCD-24-x.xx Series

Constant current is required to drive LEDs reliably. Lighting manufacturers are very often experts in light sources but have little experience with electronic components. RECOM offers a complete solution with the RCD-24-x.xx Series.

This family offers current outputs of 300, 350, 500, 600 and 700 mA which can also be adjusted using the analog dim-function. Simultaneously, the PWM –dim-function that operates at a frequency range of 20 to 200 Hz and the proving linear dimming can also be adjusted from 0 to 100%. The buck converters feature an input range of 4.5 – 36 Volts. There is also a standby function for battery operated applications. The rated accuracy of the output current is ±2% and variations due to the input voltage range are ±1%.
The housing measures just 22.1 x 12.6 x 8.5 mm and is made of UL94-V0 material. The drivers are available with either 6 pins or with four 100 mm long leads. Depending on volume requirements, it is also possible to provide customer specific versions. Operating temperature range is from -40 to 71°C (700mA) or 85°C (350 mA) without derating.
The MTBF of the 700 mA version (worst case) is of 516,000 hours at an environmental temperature of 71°C. EMC-compatibility with EN 55022 Class B is provided by the addition of two components. By using another 4 ceramic capacitors, the drivers are compatible with EN 61000 -4-2, -3, -4 und -6.
The RCD-24-x.xx Series LED-drivers are ready for use and provide a complete solution where the user does not need to deal with the compatibility problems of specific standards. Time-to-market is reduced to a bare minimum when compared with traditional IC solutions.

About RECOM Electronic GmbH:
Incorporated in 1975 RECOM Electronic GmbH originally was a supplier for high precision metal- film- resistors and- networks, becoming a pioneer for miniature DC/DC-converters in the mid 1980`s. Today RECOM is a leading supplier of converters in the power range from 0.25 Watt to 60 Watt and above.
Our core focus- development & design, production and marketing span three continents - America, Europe and Asia, thereby ensuring close proximity to our customer base worldwide. Our continued quality improvement is significantly enhanced by RECOM being the first converter manufacturer having been awarded the prestigious TS 16949 certification.
Leading international corporations have selected RECOM as their strategic supplier for power supplies. The continued expansion of our international presence makes RECOM an important partner for the global industrial automation industry, aerospace, medical, transport and communication.
The RECOM group of companies is committed to continue to be at the forefront of technological developments. Please consult our webpage:
