A80606KEV Multi-Output LED Driver

Allegro's A80606 is a multi-output LED driver for automotive applications such as exterior lighting, heads-up displays (HUD), and mid-size LCD backlighting. It implements a current-mode boost/SEPIC converter with gate driver for external N-MOSFET. This allows greater output power even at supply voltage.

The A80606 provides six integrated current sinks driving up to 180 mA per string. Multiple sinks can be paralleled together to achieve higher LED currents up to 1040 mA. The IC operates from a single power supply from 4.5 V to 40 V; once started, it can continue to operate down to 4 V. This allows it to withstand stop/start, cold crank, and load dump conditions encountered in automotive systems.
