XP Power Adds More Mini LED Drivers
LED drivers.
Sunnyvale, CA — XP Power has introduced four new models in its LDU series of PCB mount DC input constant current LED drivers. The four models offer power outputs of 5, 7, 14 and 20 Watts, these highly efficient LED drivers have a typical efficiency of 93 percent for the 5 to 14 Watt models and 95 percent for the 20 Watt devices. The LDU20 series provides up to 700mA output current, and the LDU05, 07 and 14 series has a maximum output of 1000mA. The drivers can accommodate a very wide range of input voltage from 7 to 30VDC, which needs to be at least 2V higher than the output.
Dimming options include two analog methods (voltage or resistance) and a pulse width modulation (PWM) input signal. The PWM approach has a maximum operating frequency of 1kHz, with a minimum 200ns on/off time. When using an analog dimming method, the output current range can be adjusted from 25 to 100 percent of nominal current. A remote on/off control input provides the designer the ability to control the output or sequence the start-up. All models provide protection in the event of a short or open circuit of the LED device.
The LDU series of drivers are suitable for a broad range of indoor, outdoor, underwater and automotive LED lighting applications and are also suitable for battery powered systems.
