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 and consumer appliances.
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.
