Digital and Analog Power
Electronic equipment, can not be separated from the power supply. Relative to the rapid development of MCU and RF technology, power IC development is very slow, but also from the the early linear power dominant, dominant development to the analog switching power supply, to the emergence of the digital power rewritten power market pattern.
Digital and analog power in the market, competing prevails, the respective growth. Although analog power efficiency and cost, reliability has advantages, but the lack of flexibility. Embedded MCU digital power with a certain degree of flexibility, it not only maintains high efficiency analog switching power supply, at the same time not affect the stability of the system positive feedback from the principle of eradication instability factors affect reliability, thereby reducing the power supply design and manufacturing threshold. As digital power MCU digital feedback, easy to use digital algorithms to implement complex feedback op, laid the foundation so as to further improve the performance of the power. In addition, the digital power parameter adjustment is no longer dependent on the hardware, simply re-configuration of the software, thereby simplifying the production of power, and convenient to use. Of course the MCU join, the complexity of the power of self-diagnosis technology possible, also help to improve the reliability of the electronic components.
Microchip (Microchip) recently announced the launch of world's first digital enhanced power analog controller MCP19111. It MCU, analog controller and synchronous MOSFET driver integrated in a single-chip solution, not only reduces design complexity, reduce component count and smaller footprints at the same time enhance the flexibility, it can also be 4.5V to 32V wide voltage range work. , Flexibility significantly improved compared with the traditional analog technology-based solutions. In addition, it has more advanced features, such as two-way communication or custom code support. The client device in its own IP or custom power conversion algorithm. Usual digital power MCU + MOSFET driver + MOSFET combination. But the MCP19111 available, the digital power mode will be changed to the MCP19111 + MOSFET.
However, some problems still exist in the digital power technology to promote the process. Tang Xiaoquan industry experts pointed out that, relative to the linear power and analog switching power supply, digital power work itself requires power, who provides this power? How to provide? Current power industry, from technology to process only involved in hardware, but digital power analog and digital, hardware and software integration, how to solve the coordination of analog and digital hardware and software in the design and process?
Digital power as an emerging technology will gradually occupied the analog power market, but can not replace the analog supply, like analog switching power supply through 30 years of development, has replaced most of the applications of the linear power supply, linear power is still developing, still widely used, such as LDO.
