Class D power amplifier circuit diagram, working ...
https://www.circuitstoday.com/class-d-power-amplifiers
Class D power amplifier is a type of audio amplifier were the power handling devices are operated as binary switches. Since the power handling devices (MOSFETS) works as perfect binary switches, no time is wasted in between the transition of stages and no power is wasted in the zero input condition.
How to Build a High Efficiency Class-D Audio Amplifier ...

Compared to Class A, Class B, and Class AB amplifiers, the Class D audio amplifier can reach an efficiency of up to 90-95%. Where the maximum efficiency of a Class AB amplifier is 60-65%, because they work on the active region and exhibits low power loss, if you multiply collector-emitter voltage with the current, you can find that out.

In Audio Circuits Class D amplifier circuit Class D amplifier. Class D amplifier is a type of amplifier where the power devices (MOSFET or transistor) are operated as switches. There will be only two states (ON/OFF) for these switches and no time is wasted for the transition from one stage to another.
Class D Amplifier Circuit Using IC 555 - Homemade …

As can be seen in the below class D amplifier circuit design, the IC 555 is configured as a standard astable MV mode, where the resistors Ra, Rb and C determine the frequency of the triangle waves generated at pin6/7 of the IC. The above high frequency triangle waves are compared with the music input applied at the control input pin5 of the IC.
