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, ...

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 ...

The question that arises in the design of a simple PWM DAC is what the low-pass filter pole frequency should be relative to the PWM frequency. This question is addressed by deriving the design ...

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 ...
