24W DC LED drivers in a 13.5x13.5x1.42mm footprint

May 10, 2017 //By Julien Happich
Seoul Semiconductor has developed what the company claims to be the industry’s smallest phase-cut DC LED driver series, with a power density 10X higher than conventional LED drivers.

The NanoDriver Series measures 13.5x13.5mm and is only 1.42mm high, delivered in four versions rated for 16W and 24W output power for operating LED lighting with input power of 120V or 230V (50 – 60Hz). The boards can be driven by AC or DC power supplies, they boast typical efficiencies of 85% 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).

In the future, Seoul Semiconductor will also launch the MicroDriver Series high performance drivers for LED lighting fixtures from 900 to 2400 lumens. The NanoDriver Series requires few external components and are aimed at downlight, flush mount, track and spotlight fixtures.

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.
