The MSK 4225 is a 75 V, 20 A MOSFET H-bridge PWM motor driver or amplifier. This device is suitable for DC brushed motor control or Class D switchmode amplification. All of the drive/control circuitry ...

This idea was created to solve a design problem we faced a few months ago. The circuit we were working on was used to steer an H-bridge that was controlled by a TMS320F2810 digital signal processor ...

How to use unfiltered PWM to drive high power loads. How to properly set the PWM duty cycle for high power loads. How to drive an incandescent lamp using PWM. Sometimes it’s necessary to drive a ...

What is pulse width modulation? Pulse width modulation (PWM) is a powerful digital technique for controlling analog circuits with a microprocessor’s digital outputs. PWM is employed in a wide variety ...

In previous posts, I have introduced several do-it-yourself pwm controller circuits and reviewed several Chinese PWM controller modules. The next step in this post is to share the design of another ...
