Spice model makes it easy to design with PWM amplifiersHigh-efficiency PWM amplifiers are displacing linear designs in many applications. You can design a constant-current or a constant-voltage PWM ...

ZMDI is announces three new addition to its ZSPM15xx True-Digital PWM Controller Family, designed to simplify designs and accelerate time-to-market. The ZSPM1511, ZSPM1512 and ZSPM1513, respectively, ...

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 higher ...

We mentioned Pulse Width Modulation (PWM) when talking about [sprite_tm]’s marquee control. It’s a method of power control. While [sprite_tm] did it in software, [Afroman] sent along a very straight ...

Find a downloadable version of this story in pdf format at the end of the story. Boost power converters have been widely used for Power Factor Correction (PFC) in ac-dc conversions [1] and for power ...

Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...
