1. Definition and Classification of Power Management ICs (PMIC) 1. Core Functions PMICs are analog chips, serving as the “power heart” of electronic devices, responsible for the conversion (such as AC/DC, DC/DC), distribution, detection, and control, which directly affects device performance and reliability. Typical applications include: Voltage Conversion: Converting battery voltage (e.g., 3.7V) to lower … Read more
Solid State Drives (SSDs) are continuously capturing the storage market due to their advantages of fast read speeds, low power consumption, and high data security. In particular, enterprise SSDs (eSSDs) appear to be safe and worry-free due to stringent quality control and multi-level power loss protection in data centers. However, unexpected power outages can lead … Read more
According to South Korean media,DB HiTek’s subsidiaryDB Global Chip is advancing its power management integrated circuit (PMIC) business as a new venture, but has not yet made significant progress. As competition in the display driver IC (DDI) sector intensifies,PMIC is under scrutiny to see if it can become a variable for performance improvement, with industry … Read more
