6 Strings 43V White LED Driver
General Description
The RT8569 is a high efficiency driver for white LEDs. It is designed for LCD panels that employ an array of LEDs as the lighting source. An integrated current mode boost controller drives six strings in parallel and support up-to 12 WLEDs per string. The internal current sinks support a maximum of ±2% current mismatching for excellent brightness uniformity in each string of LEDs. To provide enough headroom for current sink operation, the boost controller monitors the minimum voltage of the feedback pins and regulates an optimized output voltage for power efficiency.
The RT8569 has a wide input voltage range from 4.2V to 24V and...
