One of the primary functions of an LED driver is to ensure that the LEDs receive a constant current, which is necessary for maintaining consistent brightness and color temperature. To achieve this, many LED drivers use pulse-width modulation (PWM) to control the current flowing to the LEDs, allowing for precise regulation and dimming. Manufacturers : Sipex Corporation  |
