1. Select a dedicated PWM driver chip or module to enhance the driving ability. The external driver has higher power and current output capability and provides stronger PWM driving signal.

2. The total driving ability is increased by connecting multiple drivers in parallel, and the output signals of multiple PWM drivers are combined to the driven equipment to increase the output power.

3. Add a power amplifier circuit at the upper level of the PWM output signal to amplify the PWM signal before driving the driven equipment.
