1. How does an AC/DC converter work?
An AC/DC converter converts AC to DC through a rectifier circuit, and after filtering and voltage stabilization, it finally provides a stable DC output. Offline switching power supplies also use switching regulation technology to improve efficiency.
-
2. What are some common applications of PMIC AC/DC converters?
PMIC AC/DC converters are widely used in scenarios that require AC power to DC, such as chargers, adapters, LED driver power supplies, industrial control equipment, smart home devices, and battery management systems.
-
3. What factors should be considered when selecting an AC/DC converter?
Factors such as input voltage range, output voltage and current requirements, power efficiency, packaging, temperature range, reliability and safety certification need to be considered when selecting.
-
4. Are offline switching power supplies suitable for high power applications?
Offline switching power supplies can be used for high power applications, but proper heat dissipation and power management solutions must be designed to ensure conversion efficiency and stability. Choosing a suitable topology such as LLC resonant converter can also help achieve high power output.
