Allegro MicroSystems announces two new adjustable linear current regulators for driving automotive LED arrays. Allegro’s AEC-Q100 qualifiedA6274 and A6284 devices include many new features designed to further enhance the existing family of Linear LED drivers. These new low-EMI ICs integrate an optional pre-regulator gate drive to dynamically and linearly control an external P-channel MOSFET, which extends the output power capability of a linear LED driver by moving most of the power losses to an external power FET.
