In August 2012, Recom Asia Pte Ltd launched its buck/boost LED drivers that can deliver high voltages (up to 40 V) from a low voltage source (as low as 8 V), simplifying the lighting system with the use of a single driver and a long single string of LEDs.
Features and USP: The new RBD-12 series supplies LEDs from 3 to 20 watts with input voltages from 8 to 36 V, providing constant currents of 350 mA or 500 mA. The output voltage can be above or below the supply voltage by a factor 2 (500 mA) or by a factor 3 (350 mA), within the range from 2 to 40 VDC. These new buck/boost models are digital (PWM + remote On/Off) and analogue dimmable, and cover the temperature range -40¡ÆC to +75¡ÆC. The dimensions are 32.6 x 16.6 x 11.1 mm (L x W x H), and they weigh only 13 grams. Depending on the application, the drivers can be supplied with wires or with standard pins for PCB mounting.
