Lots of modern phones use pulse width modulation, or PWM, to manage brightness. But what is PWM, why is it harmful, and what ...
I recently published a Design Idea (DI) showing some very simple circuits for PWM programming of standard regulator chips, both linear and switching, “Revisited: Three discretes suffice to interface ...
Alright, I admit that the title is a bit over the top. So, what do I mean by it? I mean that: (1) The application of PWM control to a regulator does not significantly degrade the inherent DC accuracy ...
International Rectifier introduced a Class D audio chipset comprising the IRS20965 digital audio driver IC with protected Pulse Width Modulation (PWM) switching and a full complement of audio MOSFETs ...
Continental has been granted a patent for a method of switching electronic components using pulse-width modulation signals. The method controls output signals through control signals, adjusting them ...
Fairchild Semiconductor's FAN6920MRis an integrated critical mode PFC and quasi-resonant current mode PWM controller that meets regulatory requirements by providing >90 percent efficiency and ...
Webasto has been granted a patent for a method to check semiconductor switch faults. By evaluating current measurements or voltage pulses based on duty cycle, faults like short circuits or open ...
