A8519KLPTR-T-1 High-Efficiency Fault-Tolerant Automotive AEC-Q100 Qualified LED Driver Integrated Circuit Chip
The A8519KLPTR-T-1 is a multi-output LED driver specifically designed for small-size LCD backlighting applications. This integrated circuit combines a current-mode boost converter with an internal power switch and four current sinks, capable of driving up to 44 white LEDs (11 LEDs per string) at 100 mA. The device operates from a single power supply ranging from 4.5 to 40 V, making it suitable for automotive systems where load dump conditions may occur.
