... TM SwitchReg Description The AAT5101 is a high efficiency, 2.5W mono class D audio power amplifier. The low noise, filterless PWM architecture eliminates the output filter, reduces the external component count and system cost, and simpli- fies system design. With high efficiency 92% and the industry lowest 1 ...
