Woodward notes a PWM nonlinearity in a DI that software can't fix, and presents a potential solution: adjusting resistor ...
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 ...
An idea in an earlier blog is to make a pwm interface that can accept 5, 12 and 24V pulse streams. That one uses a bunch of resistors and has three separate inputs. Below that, wise commenter DB ...
Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude Pulse width modulation is a form of signal ...
Hello,<P>After reading a few post from <B>stickmewithneedles</B> and <B>Unobtanium</B>, I'm planning on making a thermal fan control circuit employing PWM. <P>I've no EE degree, but I love electronics ...
voltage. Often a passive single-pole RC filter will satisfy design requirements, but this approach typically suffers from several drawbacks including slow response time, noisy results, and having an ...
Pulse-width-modulation (PWM) duty cycles above 50% require a compensating ramp — called slope-compensation — to avoid instability. With traditional slope-compensation solutions, it is difficult for ...
Sometimes when a project is coming together, you need to cobble a tool together to get it completed. Whether it’s something very involved, like building a 3D printer to fabricate custom parts, or ...
High current PWM controller announcements include an 80A device from International Rectifier and a 60A chip from TI. IR’s 80A programmable two-phase interleaved pulse width modulation (PWM) controller ...
This “Product How-To” article focuses how to use a certain product in an embedded system and is written by a company representative. Light-emitting diodes (LEDs) have emerged in recent years as ...
