In this Design Idea, the total time period of an output pulse’s width is 16 times the pulse width of the input clock. The input clock connects to a binary counter (Figure 1). The output of the binary ...
Simply adding a diode and potentiometer to a 555 timer operating in the asynchronous mode yields a pulsewidth modulator (PWM) with a duty factor adjustable from 1% to 99% (Fig. 1). Applications would ...
A friend bought an electric jacket to wear on his motorcycle. But it was on all the time when it was plugged in, which made him sweaty at certain temperature ranges. He was looking for a way to ...
The DS1050 is a single 5-bit, programmable pulse-width modulator with an adjustable duty cycle from 0% up to 100%. It features a 2-wire serial port interface that supports a bi-directional data ...
Microchip announces the MCP1631 2.0 MHz, high-speed Pulse Width Modulator (PWM). The MCP1631 PWM provides a means to close the feedback loop in Switch-Mode Power Supplies (SMPSs) that use ...
[esot.eric] was trying to drive a motor and naturally thought of using pulse width modulation (PWM) to control the motor speed. However, he found that even with a large capacitor, his underpowered ...
Although the Altera MAX IIZ CPLD is a digital programmable logic device, it is versatile enough to control analog systems. This article shows how MAX IIZ CPLDs – alone or with a few passive ...
Those following the ProtoStack tutorials will be happy to hear that there is a new installment which explains Pulse Width Modulation. If you’ve never heard of PWM before, it’s a method of generating a ...
