LED Driver ICs target automotive infotainment applications.

LED Driver ICs target automotive infotainment applications.

As multi-output LED drivers for LCD backlighting, A8502 and A8514 integrate current-mode boost converter with internal power switch and multiple current sinks. LED sinks can be paralleled together to achieve higher LED currents. Operating from single power supply from 5-40 V, ICs can optionally drive external PMOS to disconnect input supply from system in case of fault. Both products offer...
