A80603-1 Overview
The A80603 and A80603-1 are multi-output LED drivers that integrate a current-mode boost converter with an internal power switch and four current sinks. The boost converter can drive four strings of LEDs at up to 120 mA, or LED sinks can be paralleled together to achieve higher currents up to 480 mA total. The devices operate from single power supply from 4.5 to 40.
