LED Light Sources are required for everything from mobile phones to navigation, monitors, televisions, and even automotive instrument clusters and driver information systems. These panels need a backlighting source, which is now dominated by LED drivers and linear LED lighting.
Allegro led lighting drivers lead the industry in reliability and robustness, offering a large selection of wide-input, Grade 0, LED Driver ICs.
The A6211 is a single IC switching regulator that provides constant-current output to drive high-power LEDs. It integrates a high-side N-channel DMOS switch for DC-to-DC step- down (buck) conversion. A true average current is output using a cycle-by-cycle, controlled on-time method.
