Market applications have put forward many technical requirements for power management chips: First, digital consumer electronic products are increasingly focused on portability and compactness, so power management ICs must have the characteristics of low energy consumption, high efficiency, small size and fast heat dissipation. Second, the cooperation between terminal product manufacturers and power management IC manufacturers is becoming closer. The speed of terminal product replacement is accelerating, and the design of power products must keep up with the development cycle of new products. Power management IC manufacturers should take the requirements of terminal product manufacturers into consideration during the product design stage and provide a complete set of solutions. Third, energy saving has always been a hot topic in the field of power management. Various countries have introduced increasingly higher energy consumption indicators. Power management products in the Chinese market will be more efficient and energy-saving. The integration of power management chips into the system will not have much impact on power management chip manufacturers, because independent power management can achieve more powerful functions. In analog circuit systems, communications, networks, smart home appliances, etc. have gradually achieved digitalization, and the last fortress to be broken is power supply. Previously, the power supply industry began to turn to switch-mode power MOSFETs, and now the trend of power digitalization may be a greater change. Power supply designers have been trying to find a power management chip that is more flexible, more reliable and has better performance under various power frequency and load conditions, and digital power supplies just meet the needs. In applications where it is simple and easy to use and does not require many parameter changes, analog power products may have more advantages, while in complex high-performance system applications with more controllable factors, faster real-time response speed, and the need for multiple analog system power management, digital power has greater advantages.
