AN1042 High Fidelity Switching Audio Amplifiers Using TMOS Power MOSFETs

AN1042/D High Fidelity Switching Audio Amplifiers Using TMOS Power MOSFETs Prepared by: Donald E. Pauly ON Semiconductor Special Consultant http://onsemi.com APPLICATION NOTE With the introduction of complementary bipolar power transistors in the late 1960s, switching amplifiers became theoretically practical. At low frequencies, bipolar transistors have switching efficiencies of 99% and will directly drive a low impedance speaker filter. The requirement for switching frequencies above 100 kHz .

AN1042 Features

* d generates rise and fall times of about 30 nanoseconds. It is designed to put out a maximum current of ±5 amp
