    产品信息

    dsPIC33EPXXGS70X/80X is a SMPS & Digital Power Conversion Digital Signal Controller. These devices offer features supporting common, multi-loop digital switch-mode power supplies (SMPS) and other digital power-conversion applications such as:

    • AC to DC Converters
    • DC to DC Converters
    • Power Factor Correction (PFC)
    • Uninterruptible power supply (UPS)
    • Inverters
    • Embedded Power-Supply Controllers
    • Arc Fault Detection
