Pulse-width Modulated DC-DC Power Converters Marian K. Kazimierczuk
Publisher: Wiley

Pulse width modulation dc motor control is one of the popular circuits in Robotics. LED lights cannot accept analog signals, so PWM is a common method of dimming LED lighting. PWM is employed in a wide variety of applications, ranging from measurement and communications to power control and conversion. What is Pulse Width Modulation (PWM) and when is it used? Low RDS(on) outputs· Overcurrent protection (OCP) Motor short protection Motor lead short to ground protection Motor lead short to battery protection· Low Power Standby mode· Adjustable PWM current limit· Synchronous rectification· Internal undervoltage lockout (UVLO)· Crossover-current protection. The LV5980MC from ON Semiconductor Corporation is a 3 A step down DC-DC converter that improves conversion efficiency at light load.

PWM is a method of controlling power to devices. Pulse-width Modulated DC-DC Power Converters epub. A4954 Designed for pulse width modulated (PWM) control of two DC motors, the A4954 is capable of peak output currents to ±2 A and operating voltages. I called this Variable Width Pulse, because of the fact that I used the modulation, which I could see on the oscilloscope, to compensate for the ripple in the rectified DC.
