LCD circuits often require a –10V voltage at 2 to 15 mA to bias a graphics-LCD-driver IC. You can usually accomplish this task with an external charge-pump IC, such as Maxim’s ICL7660, but that ...

This code was used in my bachelor's degree thesis, as part of a DC-DC source, and the code's purpose was to display a measured voltage and a reference voltage and also to generate PWM signal as a back ...

Abstract: This paper presents the common applications of PWM in electronics, and then introduces three ways to implement PWM output by using 51 Microcontrollers as an example. Using time delay to ...

Magnetic Materials are used in many application and in many different equipment for their special properties. But before using them, we need to have in-depth knowledge of their characteristics. This ...

Abstract: This paper proposed the result of the development and simulation of electrical circuit diagram, as well as the layout of PWM controller IC. The PWM controller IC was developed using HCMOS8D ...

This file type includes high resolution graphics and schematics when applicable. Sometimes a design needs more DACs than the mixed-signal microcontroller has available. An easy solution is to put in a ...

Exar Corp’s new 5A XRP7704 and 16A XRP7740 quad-PWM (pulse-width-modulation)-controller chips include gate-driver circuitry that drives external FETs. In addition to the four PWM voltage regulators, ...

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 ...

ABSTRACT: A large amount of switching loss occurs in the inverter. From this point of view, an inverter design should be optimized for which size and cost will be minimum along with increasing ...

This paper describes the development and implementation of a control system for a direct current (DC) motor using the Arduino Uno microcontroller, based on the speed and direction control of the motor ...
