Power Supplies & LED Drivers

Power supply and LED driver enquiry checklist

The load, thermal, mechanical and programme information to gather before a design-in discussion about a CC/CV power supply or LED driver.

Output and load

  • Constant current or constant voltage
  • Output voltage or current, and power
  • For LED loads: module current, string forward-voltage range and modules per driver
  • Start-up, peak or switching behaviour of the load

Input and control

  • Input voltage range and frequency at the installation
  • Dimming or control interface and range, if any
  • Exposure to surges, long cable runs or unstable supplies

Thermal and mechanical

  • Mounting position and available space, with a drawing if possible
  • Measured or expected temperature at the supply or driver position
  • How heat leaves the host product
  • Ingress protection the host product needs

Validation and programme

  • Approvals the end product needs and who will hold them
  • Validation plan, acceptance criteria and sample quantities
  • Expected volumes and the timing of prototype, pilot and production
  • Change-notification expectations and expected production life

Mention in the enquiry any drawings or draft requirement document that exist, even if incomplete; they are requested when the review begins. Requirements are recorded as a baseline with a revision, so later changes can be tracked.

The selection guide for power supplies and LED drivers explains each decision. Start the discussion through the enquiry form.
