R1700 系列
650V 边缘谐振控制,零电压开关 (ZVS) PFC/LED驱动控制芯片

  • 概述

    The R1700 is a zero-voltage switching (ZVS) PFC/LED driver controller with a variable output current/voltage. It is ideal for improving power factors of LED lightings.

    This device features the arbitrary setting of output voltage based on buck-boost (inverting) topology.

    Integration of this device and the R1580 allows the two-stage architecture and a flicker-free operation in LED lighting applications.


    • Edge Resonant Control of ZVS helps to achieve Low Switching Loss and Low EMI.
    • R1700 is capable of Arbitrary Setting an Output Voltage based on Buck-boost (Inverting) Topology.
    • Integration of R1700 and R1580 realizes Flicker-free Operation in LED Lighting Applications.
