Figure 1 Analog PWM circuit using triangle wave generator and comparator. In this Design Idea, we show an alternative circuit. It uses very little power, can be implemented in a small silicon area, ...

As previously stated, if you compare the sawtooth voltage with a constant voltage using a comparator, you get a PWM signal at the comparator’s output. That is exactly what I made. So, a PWM signal is ...

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 x10 approach allows you to generate a range of duty cycles(10-90% in 10% steps) vs only 10% & 50% when using x1 as in your comment. 30% or 40% would be more common for IR remote control.

LED-driver circuits can be dimmed by applying a variable duty cycle (pulse-width modulation, or PWM) to the LED. PWM exploits LED behavior: At higher current levels, the LED’s light output is ...

Converting this dc voltage to a low-frequency (e.g., 170 Hz) PWM signal (fixed-frequency, variable-duty-cycle square-wave) requires a PWM signal generator. But if the inverter controller doesn't ...

Dual channel PWM controller. Intersil has announced the ISL6539, a dual PWM controller IC with built-in protection and monitoring in a single IC. The controller accepts an input voltage from 5V to 15V ...

He figured he get the fan to shut off by tweaking the PWM signal, but he found that he could not get the duty cycle under 20% using software, which still caused the fan to run at all times.

Microchip Enhances Digital Signal Controller Lineup with Industry-Leading PWM Resolution and ADC Speed Microchip Technology Inc. Wed, Jun 18, 2025, 4:02 AM 4 min read ...

CHANDLER, Ariz., June 18, 2025 (GLOBE NEWSWIRE) -- Evolving security and functional safety demands, coupled with the growing complexity of real-time embedded applications, are driving designers to ...
