PWM waveforms are commonly used to control the speed of DC motors. The mark/space ratio of the digital wave-form can be defined either by using an adjustable analogue voltage level (in the case of a ...
In IC design, the typical approach for generating a pulse width-modulated (PWM) signal from an analog value (such as in the control loop for a switch mode power supply) uses a ramp or triangle wave ...
Linear Technology has unveiled a new pulse width modulation (pwm) generator with 48 independent channels. According to the IC specialist, each channel has an individually adjustable 12bit (4,096 steps ...
The LT3954, a DC/DC converter designed to operate as a constant-current source and constant-voltage regulator with an internal 5A switch, is now available from Linear Technology. The LT3954, a DC/DC ...
I have had an on-going mission to design a universal-ish pcb that will convert a PWM waveform at one frequency into to another frequency while retaining the mark-space ratio. The obvious answer is a ...
This file type includes high resolution graphics and schematics. You can build an analog calculator using a pulse-width modulator (PWM) to perform accurate four-quadrant multiplication and division.
