Typical Application-2 for RT8567A, 6-CH, 43 Vout WLED Driver with PWM Dimming Control. 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
