The R1700V 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 and consumer appliances. This device features the arbitrary setting of output voltage based on buck-boost (inverting) topology. Integration of this device and the R1580N allows the twostage architecture and a flicker-free operation in LED lighting applications.
