The RT8567A 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 supports 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.资料下载
