The LEDC10 series dc/dc drivers target LED lighting applications with output ratings up to 10W. The LEDC10-12-R48, a non-isolated, constant-current LED driver housed in a SIP, operates with an input of from 4.5 to 20 Vdc and provides a programmable constant-current output from 0 to 480 mA with a drive voltage from 3V to 20V. PWM LED light-dimming is an additional feature of these drivers. The constant-current output range is programmable via external logic levels or jumpers connected to trim pins on the driver. In addition, LED light-dimming control is accommodated via a PWM control input with a duty cycle range of 10% to 100% or by using the logic level trim inputs. All models in the series are convection cooled and can operate in ambient temperatures from -40°C to +85°C at full load without derating. Typical efficiencies are 87%. Other standard features include over-current and over-voltage protections. Pricing starts from $17 each/1,000. TDK-LAMBDA, San Diego, CA. (800) 575-4400.
