LED Drivers Achieve 1V Dropout

Poised for low-voltage LED lighting designs, the CL520 and the CL525 linear, constant-current two-terminal LED drivers specify a 1V dropout and deliver fixed output currents of 20 mA and 25 mA, respectively. Both feature temperature compensated output currents to maintain consistent LED brightness regardless of temperature. With maximum ratings of 90V, they can withstand transients without any additional protection circuitry when deployed as recommended. Both devices are available in TO-92 (CL520N3-G, CL525N3-G) and D-PAK (CL520K4-G, CL525K4-G) packages and are both green and RoHS compliant. Prices for the CL520 and the CL525 are $0.33 and $0.47 each/1,000, respectively. For further information, call SUPERTEX INC., Sunnyvale, CA. (800) 222-9883.
