PCB Mount LED Drivers
The LDD products provide selectable output current options of 300 / 350 / 500 / 600 / 700 / 1000ma to choose. Their typical deployment is to connect to the output of a CV (constant voltage) mode power supply and provide a constant current to drive LED strings. The LDD series maintains accurate current balance for each LED string ensuring the the long life of the LEDs and eliminates the need to sort the Vf value of LEDs. The independent constant current nature of any LED string driven by the LDD series won’t affect the others.
The non-isolated Buck topology of the LDD series possess up to 97% of efficiency and can operate between -40~+85C with free air convection (up to 71C for 600mA~1A models). Built-in EMI filters comply with EN55015 lighting regulations without any external components for convenient PCB installation. Standard functions include PWM dimming, protections of short circuit and over temperature, wide range of input/output voltage. Fully encapsulated packaging provides protection from dust and moisture and makes these products suitable for applications including street lighting, landscape lighting, tunnel lighting, household lighting, and all kinds of indoor/outdoor LED lighting.
