General Description

The RT8464 is an isolated secondary side 6-CH LED driver that delivers well matched LED current to each channel of LED strings.

A built-in optocoupler driver supports the transformer primary side control circuit to regulate the LED current.

The LED current is linearly controlled by a high gain amplifier that drives the optocoupler to control the primary side, thus making the conventional secondary DC/DC PWM switching stage unnecessary.
