Microchip’s AT9933 is a variable frequency PWM controller IC, designed to control a LED lamp driver using a low-noise boost-buck topology. The device is ideally used for LED lamps and other LED ...

The ISL95825 is a three-phase PWM controller IC designed for VR12.5™/VR12.6™ CPUs. The device offers control and protection for voltage regulators (VRs). The voltage regulator is configurable in 3, 2, ...

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 ...

Variable speed drives (VSDs), sometimes also known as variable frequency drives, are electronic devices used to regulate the speed of an ac induction motor. Electric motors consume approximately 25% ...
