A constant voltage driver regulates a specified output voltage. Designs using constant voltage supplies will need to regulate the current in their system. This can be advantageous in applications where the total number of LEDs for an installation is unknown or where added control is desired.

A constant current driver regulates a specified output current. Designs using constant current are able to easily connect the driver’s output directly to LEDs without added regulation. This is possible because LEDs respond directly to the current driven through them.

A constant power driver is a constant current driver in which the output current can be modified. As the output current setting decreases, the output voltage increases allowing for the same rated output power. This allows for more freedom of design over drivers that derate as the output current decreases. For more information, see “Understanding the I-V Operating Area of Constant Power Drivers” in our Design in Guide.

The 0-10V and DALI programmable drivers utilize the PRG-MUL2 to interface with a computer. Written and video instructions are available to assist with downloading the software. For more information about using our interface, see “Programming” in our Design in Guide or view our additional walk-through videos.

The best driver for any given design will depend on the load and the application. With this information, the application will define which features are needed for a design and ultimately which driver will be best. For more information, see “Defining Application Requirements to Select the Best LED Driver Family” in our Design in Guide or contact your local technical support for their recommendation.

Dim-to-off is the ability for the driver to dim to a minimum dimming percentage and then to “off” where no current will be output causing the drivers to no longer illuminate. Though the driver is “dimmed-to-off”, the driver is still on and consuming typically < 0.5W. It is similar to the sleep mode on a computer.

Tc stands for case temperature. The Tc for safety is a temperature that is defined by the safety agency during safety evaluation. The Tc for warranty is based upon the correlated temperature and lifetime of the capacitors used within a design. For example, a design may be safe to operate with a case temperature of 90°C, but the components will not be able to withstand long-term operation with a case temperature of 90°C.
