Overview
LM4651 & LM4652 Overture™ 170W Class D Audio Power Amplifier Solution August 2000 LM4651 & LM4652 Overture™ Audio Power Amplifier 170W Class D Audio Power Amplifier Solution General Description The IC combination of the LM4651 driver and the LM4652 power MOSFET provides a high efficiency, Class D subwoofer 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 IC’s 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 IC’s keep the PCB area small and aids in EMI control.
The near rail-to-rail switching ...
