Lm4651 & Lm4652 Overture?⠁udio Power Amplifier 170w Class D Audio Power Amplifier Solution - National Semiconductor

The IC combination of the LM4651 driver and the LM4652 Power MOSFET provides a high efficiency, Class D sub- woofer Amplifier solution. The LM4651 is a fully integrated conventional pulse width Modulator driver IC. The IC contains short circuit, under voltage, over modulation, and thermal shut down protection circuitry. It contains a standby function, which shuts down the pulse width modulation and minimizes supply current. The LM4652 is a fully integrated H-bridge Power MOSFET IC in a TO-220 power package. Together, these two ICs form a simple, compact high power Audio Amplifier solution complete with protection normally seen only in Class AB Amplifiers Few external components and minimal traces between the ICs keep the PCB area small and aids in EMI control. The near Rail-to-Rail switching Amplifier substantially in- creases the efficiency compared to Class AB Amplifiers This high efficiency solution significantly reduces the heat sink size compared to a Class AB IC of the same power level. This two-chip solution is optimum for powered subwoofers and self powered speakers. By National Semiconductor Corporation
