hieved. Degree in applied busy 50% of full current up to 50% brightness. To ensure that the human eye can not see the PWM pulse, PWM signal frequency must be higher than 100Hz. Maximum PWM frequency depends on the power supply startup and response time. To provide maximum flexibility and ease of integration, LED drivers should be able to accept the PWM frequency up to 50kHz.

In constant current mode operation power supply need to adopt over-voltage protection function.
