Programmable LED drivers from TDK-Lambda for lighting applications

TDK-Lambda has introduced the new LEDC10 series of DC-DC LED Drivers that are designed for LED lighting applications with output ratings up to 10-watts. The LEDC10-12-R48 is a non-isolated, constant-current LED driver housed in a compact single in-line package (SIP). They operate with a DC input range of 4.5V to 20Vdc and provide a programmable constant-current output of 0 to 480 mA with a drive voltage of 3V to 20V.

The drivers constant-current output range is programmable via external logic levels or jumpers connected to trim pins on the driver. The LED light-dimming control is also accommodated using a PWM control input with duty cycle range of 10% to 100% or by using the logic level trim inputs. Applying different combinations of logic "1" and "0" levels to the trim inputs, the maximum output drive current will change to 50mA, 150mA, 350mA, and 480mA. These drivers are convection cooled and can operate in ambient temperatures from -40°C to +85°C at full load. Other standard features include overcurrent and overvoltage protections. The SIP drivers measure only 1.26" wide x 0.60" high x 0.33" thick and weigh just 6 grams.

Price: Each US$17 in 1,000 piece quantities.
