General Description

The A6270-1 is a linear, programmable current controller capable of accurately regulating LED current in two strings with external MOSFETs.

The LED current can be switched between high current and low current for Stop/Tail or DRL/position applications.

The two LED current levels from each output are set by two sense resistors.
