PWM Controllers:

element14 offers an exclusive range of PWM controllers. Engineers can choose one based on switching efficiency, input voltage range, voltage topologies, duty cycles, maximum current capacity, and thermal performance.

Pulse-width modulation, or PWM, is a modulation technique that changes the width of the pulse signal in electrical systems to regulate the average power supplied to a load. PWM is particularly helpful for effective output regulation of audio amplifiers, the motor speed, and the brightness of light. They are frequently used in specialized PWM controller integrated circuits (ICs) and microcontrollers. Modern PWM controllers offer increasingly sophisticated power management solutions that meet the growing demand for energy-efficient, compact electronic systems.

Key applications include voltage regulation in computer power supplies, LED dimming, motor speed control, and battery charging systems. Advanced PWM controllers incorporate adaptive switching frequencies, programmable output levels, and integrated protection mechanisms against overcurrent, overtemperature, and short-circuit conditions.
