This Product Selection Guide contains information to help select products in the LED Drivers category on DigiKey.com
LED drivers provide a constant current, constant voltage, or a combination of both to provide a steady flow of power to residential or commercial LED lighting elements. Topologies include AC to AC, AC to DC, boost, buck, and buck-boost. Because they can accept a wide range of input voltage, LED drivers are selected by choosing the minimum and maximum input voltage, the output voltage and current (max), the overall power output, and dimming features.
SelectionCharacteristics
DigiKey Programmable: DigiKey can program verified products prior to shipping. For unverified products, please inquire with ProgCent.Techs@digikey.com
Type: Indicates the style and configuration of the device.
Topology: Indicates the basic circuit configuration of the device, determining core aspects of its functionality and behavior.
Number of Outputs: Indicates the number of separate outputs the device can provide.
Voltage - Input (Min): This represents the minimum voltage rating to which a device will meet its given specifications.
Voltage - Input (Max): Typically this represents the maximum voltage rating to which a device will meet its given specifications. Exceeding this voltage rating may damage the device and other system components.
Voltage - Output: Nominal value of voltage for output.
Current - Output (Max): The maximum amount of current that can be output by the device.
Power (Watts): Maximum amount of power the device can provide - due to losses you generally want your applications power needs to be between 40%-60% of what your power supply can provide.
Voltage - Isolation: The maximum voltage difference that can be observed across the device’s isolation barrier before breakdown occurs and isolation is lost.
Dimming: Indicates if a device includes provisions for varying the electrical output delivered to a load in an end application. May also describe the means by which a desired output set point is communicated to a device.
Features: These are different capabilities or properties of the device such as OCP (Over Current Protection) or OVP (Over Voltage Protection).
Ratings: Minimum performance standards of the device, which are typically set by a third party.
IP Ratings
IP (Ingress Protection) ratings such as (IP20, IP65, IP67, etc.) define how likely water and dirt will get into the system. The first number represents dirt and solid contaminants while the second represents water and liquids.
| Solids | Liquids | |
|---|---|---|
| 1 | Protected against solids larger than 50mm. | Protected against vertically falling drops of water. Limited Ingress permitted. |
| 2 | Protected against solids larger than 12.5mm. | Protected against vertically falling drops of water with the enclosure tilted up to 15 degrees from vertical. Limited ingress permitted. |
| 3 | Protected against solids larger than 2.5mm. | Protected against spraying water up to 60 degrees from vertical. Limited ingress permitted for 3 minutes. |
| 4 | Protected against solids larger than 1mm. | Protected against water splashed from any direction. Limited ingress permitted. |
| 5 | Protected against dust. Limited ingress of dust permitted. | Will not affect operation of equipment 2-8 hours. Protected against jets of water. Limited ingress permitted. |
| 6 | Dust tight. No ingress of dust 2-8 hours. | Protected against powerful jets of water. Limited ingress permitted. |
| 7 | ______________________ | Protected against the effects of immersion in 15cm-1m for 30 minutes. |
| 8 | ______________________ | Continuous immersion in water up to 3m for long periods of time. |
| 9 | ______________________ | Protected against high pressure jets of hot water. (30 seconds) |
| 9K | ______________________ | Protected against high pressure jets of hot water. (2 minutes) |
Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.
Efficiency: Ratio of output power to input power, typically measured at nominal voltage under full load.
Termination Style: Selection of termination style used to connect the device to a system, such as connector, screw terminals, or wire leads.
Size / Dimension: The physical dimensions of the power supply - typically length, width, and height or diameter and height.
Approval Agency: Meets the minimum safety standards of the approving agency. These agencies are either government entities or private third-party labs that protect consumer safety.
Standard Number: An indication of the agency safety standard(s) that the item meets.
