Working Principle

The SP6685ER-L/MTR is a dual-channel LED driver with low voltage requirements and a wide operating temperature range. It provides precise LED color control and adjustable dimming ratios up to 11:1. The working principle of the SP6685ER-L/MTR is based on a DC-DC buck converter, which is designed to convert incoming voltage from the capacitors into a regulated low-voltage output. The microcontroller or other software is then used to control the PWM signal, which controls the on/off period of the PWM signal to control the LED current. This system allows precise control of the LED output and its color. The SP6685ER-L/MTR also includes an overvoltage protection circuit, which prevents overvoltage conditions that can cause damage to the LEDs. This protection circuit also helps reduce the power dissipation of the driver.
