A simple oscilator with PWM that can be used to control speed of motors or light intensity. (4/29/2006)
This DC power supply controller is controlled by pulse width modulation PWM, generated by the circuit around timer IC2 7555 according to the formula: Du
Using a CMOS version of the 555 timer, this circuit can be used to control the speed of a motor by adjusting the duty cycle of the pulses sent to the motor
In todays highly competitive electronics environment, designers are constantly looking for ways to reduce overall system costs. One of the most commonly asked questions that analog specialists at digital microcontroller (MCU) companies hear from customers is, is the almost cost-free Pulse-Width-Modulation (PWM) Digital-to-Analog Converter (DAC) good enough for my application, or do I need a higher-performance, standalone DAC instead?.......

CS3842AAN/D Single CS3842A Provides Control for 500 W/200 kHz Current-Mode Power Supply http://onsemi.com APPLICATION NOTE INTRODUCTION With the introduction of the CS3842A PWM IC, currentmode is possible for power [. . ]
When the potentiomenter is all up, the Rcharge resistance is 1, 0 Kohm (the diode prevents the capacitor to charge through the second potentiometer section and the other 1, 0 Kohm resistor) , and Rdischarge is 21 Kohm, giving a 5% on duty cycle and a 1Khz frequency.
PWM drivers are used in analysing, testing, installing and powering all kinds of electronic and electrical devices. We have published a few designs.
