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