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.
