General Description
The A6214 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.
