More About Digital Power Conversion
Traditional power conversion products, such as light ballasts, inverters and AC-DC/DC-DC power supplies have employed an analog control loop for basic control of the PWM module, integrated circuits (ICs) and power devices. In these types of power products, additional digital control and communication performed by a microcontroller has been layered on top. In digital power conversion, however, the analog control loop is replaced with a digital control loop, and the PWM module is typically integrated into the same microcontroller that is performing the high-level control and communication.

By using digital loop control to implement power conversion, developers can realize many benefits. These benefits are enabled by the ability to perform power-conversion control via reprogrammable software, as well as the performance and features offered by a digital solution.

Designers using new, flexible DSCs for digital power conversion are experiencing newfound abilities to innovate. For more information on Digital Power Conversion Solutions from Microchip, visit [2] www.microchip.com/SMPS.
