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 sub-  
woofer amplifier solution.  
Key Specifications

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.  
100dB (Min)  
Features  
n Conventional pulse width modulation.  
n Externally controllable switching frequency.  
n 50kHZ to 200kHz switching frequency range.  
n Integrated error amp and feedback amp.  
n Turn−on soft start and under voltage lockout.  
n Over modulation protection (soft clipping).  
n Short circuit current limiting and thermal shutdown  
protection.  
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.  
n 15 Lead TO−220 isolated package.  
n Self checking protection diagnostic.  
Applications  
n Powered subwoofers for home theater and PC’s  
n Car booster amplifier  
n Self-powered speakers
