The A8510 is a multi-output white LED driver for LCD backlighting. It integrates a current-mode boost converter with internal power switch and 8 current sinks. The boost converter can drive up to 96 LEDs with 12 LEDs at 40 mA per string. The LED sinks can also be paralleled together to achieve even higher LED currents, up to 320 mA. The A8510 can operate from a single power supply, from 5 to 40 V.
If required, the A8510 can drive an external P-FET to disconnect the input supply from the system in the event of a fault. The A8510 provides protection against output short and overvoltage, open or shorted diode, open or shorted LED pin, and overtemperature. A dual level cycle-by-cycle current limit function provides soft start and protects the internal current switch against high current overloads.
The A8510 has a synchronization pin that allows PWM switching frequencies to be synchronized in the range of 600 kHz to 2.25 MHz.
The device package is a 26-contact, 4 mm × 4 mm, 0.75 mm nominal overall height QFN, with exposed pad for enhanced thermal dissipation. It is lead (Pb) free, with 100% matte tin leadframe plating.
