Applications
The RECOM RCD-24-0.70/PL/B is used in industrial and commercial LED luminaire driver boards where a regulated 700 mA constant current must be delivered from a 24 V DC bus with high efficiency. Its 96% efficiency and SMD-6 package make it ideal for embedded LED engine modules in smart lighting controllers, architectural lighting drivers, and plant-growth LED panels. The wide 4.5 V to 36 V input range also supports battery-powered portable lighting and solar-powered off-grid LED systems that operate from unregulated voltage sources.

Frequently Asked Questions
What output current and input voltage range does the RECOM RCD-24-0.70/PL/B provide, and which LED string configurations does it support?
The RCD-24-0.70/PL/B delivers a regulated 700 mA constant output current from an input voltage range of 4.5 V to 36 V with a 24 V nominal input. This 700 mA output current suits LED strings composed of high-power 1 W or 3 W LEDs wired in series, where consistent current control is critical for uniform brightness and long LED lifetime. The 4.5 V to 36 V input window allows the module to operate from 12 V automotive rails, 24 V industrial buses, or unregulated rectified supplies without an upstream pre-regulator.
How does the 96% efficiency of the RCD-24-0.70/PL/B reduce thermal management requirements in LED luminaire designs?
At 96% efficiency and 700 mA output, the RCD-24-0.70/PL/B dissipates only about 4% of input power as heat — approximately 67 mW at 24 V input and 700 mA output. This low dissipation allows the SMD-6 package to operate without a heatsink in most ambient conditions up to 50°C, unlike lower-efficiency drivers that may require thermal vias or external heat spreaders. The reduced thermal burden also improves overall LED luminaire reliability, since LED driver failures are commonly caused by elevated junction temperatures in the switching components.
What certifications does the RCD-24-0.70/PL/B hold, and how do they simplify compliance for LED lighting products sold in North America and Europe?
The RCD-24-0.70/PL/B holds both EN (European Norm) and UL (Underwriters Laboratories) approvals, which are the primary safety certifications required for LED drivers used in luminaires sold in the EU and North American markets respectively. Using a pre-certified driver module reduces the end-product certification burden by allowing the luminaire OEM to reference the driver's existing certification instead of performing full driver-level safety testing. REACH compliance is also confirmed, enabling the product to be sold in EU markets without restricted substance exemptions.
How does the SMD-6 package of the RCD-24-0.70/PL/B compare to through-hole LED driver modules in terms of assembly and board density?
The SMD-6 package of the RCD-24-0.70/PL/B has a footprint of approximately 10 mm × 7 mm (6-pad no-lead configuration), which is roughly 30% smaller than an equivalent through-hole DIP-8 driver module. Surface-mount placement enables automated pick-and-place assembly at rates above 5000 parts per hour on standard SMT lines, eliminating the hand-insertion steps required for through-hole modules. The flat no-lead package also provides lower thermal resistance to the PCB pad compared to leaded through-hole packages, improving heat spreading into the board for the 700 mA output current.
