Unique Power Supply for Automotive Audio Power Amplifier 910796

ABSTRACT

The pursuit of high performance sound systems demands increased power. Traditional approaches include bridge mode amplifiers and dc to dc step-up converters to achieve higher power outputs. Bridge mode amplifiers are now widely used. Cost, efficiency, and reliability are factors limiting the application of step-up converters. An integrated monolithic approach can overcome these limitations. Theoretically, this topology could yield an output in excess of one hundred and fifty Watts into a four ohm load.
