Unique Power Supply for Automotive Audio Power Amplifier 910796
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.
