High Efficiency Step Down LED Driver for High Brightness LED and OLED
8. Application
8.1. Thermal Precautions
When operating at elevated ambient temperature, vertical mounting in an air volume
sufficiently large enough to allow convection is recommended to reduce surface temperature
of the regulator. Additional cooling measures can help to further reduce the regulator
temperature and increase long term reliability. No part of the module surface may exceed
125°C during the operation at any time.
8.2. Failure Modes
The most common failure mode occur when the regulator is destroyed due to over
temperature, overvoltage, or an internal short circuit that causes the fuse to disconnect. The
fuse has the ability to disconnect failure currents up to 50A and will start to trip at 1A.
8.3. Recommended Safety Measures
Materials with low flash points must be kept away from the regulator. The surface temperature
of parts on the regulator may reach up to 125°C surface temperature when used at elevated
ambient temperatures and maximum power.
