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. By 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 finally 480mA.
All models are convection cooled and can operate in ambient temperatures from -40°C to +85°C at full load without deratings. Typical efficiencies are 87%. 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. All units come with TDK-Lambda’s industry leading 3-year warranty.
