Amplifier Electronic Circuits – Audio Amp Schematics 170w – LM4651 & LM4652

IC LM4651 and LM4652 is a type of MOSFET ICs and power amplifiers include high-efficiency amplifier, suitable for self-powered speakers, a subwoofer and driver quality car. LM 4651 is a fully integrated conventional pulse width modulation (PWM) driver, contains undervoltage, short circuit, overmodulation. The maximum efficiency of this circuit is 85% at 125W in standby […]

Determining the optimum PCB layout

One of the keys in determining the optimum printed circuit board layout is to understand how and where the signal return currents actually flow,  Most designers only think about where the signal current flows  and ignore the path taken by the return current. we must understand how the high frequency current flows in a conductor.
