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.

A8510 Wide Input Voltage Range, High Efficiency Fault Tolerant LED.

Integrated 2 MHz capable boost converter with 60 V DMOS switch with OVP protection.
Sync function to synchronize boost converter switching frequencies up to 2.3 MHz.
LED current up to 40 mA per LED channel into 8 channels.
Drives up to 12 series LEDs in 8 parallel strings (Vf = 3.5 V, If = 40 mA), VIN = 8 V, switching frequency of 1 MHz.
Single EN/PWM pin interface for PWM dimming and enable functions.
APWM pin for fine-tuning color adjustme.
