Description:Flat disc LED lamps: ROHM's lamp LED lineup covers various types including high-brightness/high-reliability LED lamps suitable outdoor displays.
ROHM recommends a thermal pad on the bottom of the package, connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended, and the thermal pad should be connected to a ground plane to reduce thermal resistance.
To ensure reliable operation in high-temperature environments, it's essential to follow the recommended operating conditions, including derating the output current and voltage according to the temperature. Additionally, consider using a heat sink or thermal management system to keep the junction temperature below 125°C.
ROHM recommends using a low-ESR ceramic capacitor (X5R or X7R dielectric) with a value between 4.7μF to 10μF for the input capacitor. This helps to reduce input ripple and ensure stable operation.
To prevent EOS damage, follow proper handling and assembly procedures, including using an anti-static wrist strap or mat, and avoiding direct contact with the device pins. Additionally, ensure that the PCB is properly cleaned and dried before assembly to prevent moisture-related damage.
ROHM recommends using a low-ESR ceramic capacitor (X5R or X7R dielectric) with a value between 10μF to 22μF for the output capacitor. This helps to reduce output ripple and ensure stable operation.
