A6270-1 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.
