Beschreibung
- Parallel Typical Application of two A8509s, overvoltage protection on master must be set higher than the OVP on the slave for A8509 WLED Driver. The A8509 is a multi-output white LED driver for backlighting LCD panels. It integrates a current-mode boost controller and four individual current sinks. The boost controller architecture allows for significant scaling of boost voltage to optimize the solution for the required number of LEDs per string. The FSET/SYNC pin either sets the required boost switching frequency or synchronizes the value in the range of 300 to 800 kHz
