Linear current regulators drive automotive LED arrays

Linear current regulators drive automotive LED arrays
Designed to drive automotive LED arrays, two series of adjustable linear current regulators hve been announced by Allegro MicroSystems Europe. The AEC-Q100 qualified A6274 and A6284 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.
