As electronic devices continue to evolve towards greater intelligence and performance, the demand for efficient and reliable power solutions is rapidly increasing. Digital power is gaining more attention in the market and is widely applied across various fields.

Compared to traditional analog power, digital power features higher efficiency, precision, power factor, and stability. It enables more accurate control of voltage and current and offers improved dynamic response and closed-loop control advantages, which overall enhance system efficiency, allow higher power output, and meet customer requirements for smaller product sizes.

The following image compares traditional PFC circuit structures with totem-pole PFC structures, showing a significant improvement in efficiency with the totem-pole PFC.

Nuvoton Technology offers dedicated MCUs and comprehensive reference designs for the digital power market. The digital power control MCU is distinct from general-purpose MCUs, requiring higher computational power and reliability. It also requires precise PWM and high-speed ADC capabilities to enable fast closed-loop control systems for detection, feedback, computation, and real-time control.
