The A8513 is a single-output white LED WLED driver for LCD backlighting. It integrates a current-mode boost converter with an internal power switch and one current sink. The A8513 can operate from a single power supply from to 40 V, to accommodate start/stop, cold crank, and load dump requirements. A 2 MHz boost converter switching frequency allows the A8513 to operate above the AM radio band.

If required, the fault flag can be used as part of a circuit to drive an external P-FET to disconnect the input supply from the system in the event of a fault. The A8513 provides protection against output short and overvoltage, open or shorted diode, open or shorted LED pin, shorted boost switch or inductor, shorted ISET resistor, and IC overtemperature. A dual level cycle-bycycle current limit function provides soft start and protects the internal current switch against high current overloads.

The A8513 is provided in a 10-pin MSOP package suffix LY and a 16-pin TSSOP package suffix LP . Both packages have an exposed thermal pad for enhanced thermal dissipation, and are lead Pb free, with 100% matte tin leadframe plating.
