I’ve encountered a limitation when using PWM on the RP2040 with the Mbed-based Arduino core: It seems impossible to set a PWM frequency below ~500Hz. This effectively restricts the usable PWM range, ...

Abstract: This paper proposes a low power digital PWM buck converter with a clock-gating shift-register. The digital PWM controller of the digital buck converter adjusts the PWM duty ratio using a ...

I2C_PWM_generator is a sketch to change an Arduino UNO in an I2C slave device to control the 6 PWM outputs of the Arduino UNO. One can think of this sketch as a co-processor that handles the 6 PWM ...

The 12 new digital controllers provide up to seven phases assignable in any combination across two outputs, and combine with smart power stages to provide a scalable solution from 10A to 450A.

Abstract: The paper presents performance analysis and optimization of digital pulse width modulation (PWM) techniques for surface-mounted permanent magnet synchronous motors (SPMSM). Three specific ...

International Rectifier, IR®, a world leader in power management technology, introduced its highly versatile family of CHiL digital PWM controllers that dramatically shrinks footprint and improves ...

The iW1700 zero-power ac/dc digital PWM controller targets 120/230-Vac offline adapters and chargers (up to 5 W), which consume zero no-load power for cell phones, audio players, digital cameras, and ...
