RT8464
Isolated Secondary Side 6-CH LED Driver with Optocoupler Driver
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.
The RT8464 selects and regulates the LED strings with the highest
voltage, hence it allows
voltage mismatches between LED strings.
The RT8464 automatically detects a...
