What is duty cycle? Duty cycle is defined by the percentage of high voltage duration in a complete digital pulse. If the duty cycle is 50%, then it will remain on for exact half the duration of the ...

Pulse Width Modulation (PWM) is a basic concept that is employed in many areas of electronics. PWM is a simple averaging method that is used in everything from microwave power percentages to LED ...

Last time, I showed you a simple PWM block and an open source UART core. This time, I’ll put these parts together to create a PC PWM output peripheral. With working code (working, at least, in ...

Transient response is a key performance parameter for the multiphase voltage regulator, especially in microprocessor applications. Conventional pulse-width modulation (PWM) schemes have delay times ...

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 ...

This circuit transforms a pulse-width-modulation (PWM) signal into non-overlapping clock signals, whose number depends on the length of a shift register. These clock signals can be used to power up ...

[Thomas] wanted to play around with a few high-power LEDs and a RaspberryPi. LED controllers usually require some form of PWM to change the brightness of a LED, and unfortunately the Pi only has one ...

Precise configuration is simple with a convenient USB connection to a PC. Other features include an operating temperature range of -40 to 80 °C (32-176 ºF), electrical noise immunity, and surge ...
