Pulse Width Modulator, 100 Watt
This is a state-of-the-art surface mount 100 Watt Pulse Width Modulator (PWM).
PWMs are excellent tools for a variety of applications, including:
- Driving a DC Motor -- will allow you to vary its speed
- Robotics -- will allow you to drive your main motor smoothly and precisely
- LED driver -- will allow you to control light intensity
- Dimmer for low voltage incandescent lighting (with a little modification)
- HO Train controller -- will allow you to vary train speed
- Ultrasonic -- will allow you to vary its speed
The PWM is generated with an 8 Bit, CMOS Microprocessor which generates extremely accurate pulses.
