Seoul Semiconductor reports development of the industry’s smallest phase-cut DC LED driver series measuring 13.5mm x 13.5mm x 1.42mm. The NanoDriver Series has a power density 10X higher than conventional LED drivers and is available in four versions rated for 16W and 24W output power for operating LED lighting with input power of 120V or 230V (50 – 60Hz).
The world’s smallest miniature converter can be driven by AC or DC power supplies and features an IC directly attached to the substrate, dramatically reducing device size. The smaller footprint will enable designers to reduce the size of light fixtures by as much as 20%, which in turn lowers shipping and storage costs.
Suitable for LED assemblies operating at input voltages of 120V or 230V (50 – 60Hz), the drivers have typical efficiencies of 85 percent and power factor correction (PFC) of <0.9, and are rated for inrush current of <300mA, with an over-temperature protection feature that limits the LED current at temperatures above 160°C. Operating temperature range is -40° to +70°C (ambient) and -20° to +85°C (at TC point).
The NanoDriver Series is ideal for downlight, flush mount, track and spotlight fixtures. Their small size enables ultra-thin and novel fixture designs in wall sconces, making conventional lamp replacement possible without the need for a large volume recess for the driver, or a reduction in the light output.
The drivers are UL recognized, provide flicker-free, low ripple current operation for phase-cut dimmers, and are compliant to California Title 24, enabling lighting designers to meet the most challenging design requirements, including low flicker, high power factor, Class B EMI and 2kV surge.
In the future, the company plans to launch the MicroDriver Series high performance drivers for LED lighting fixtures from 900 to 2400 lumens. The MicroDriver Series is designed with a miniature package that reduces the size of the converter by more than 10X to enable the integration of the control circuitry with the external driver, making it possible to mount more light sources on the board, or reduce the size of the board.
