R1700V Series
650 V Variable Output Current/Voltage ZVS PFC/LED Driver Controller
No. EA-364-180312
OVERVIEW
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 two-
stage architecture and a flicker-free operation in LED lighting applications.
KEY BENEFITS
●
●
●
Edge Resonant Control of ZVS helps to achieve Low Switching Loss and Low EMI.
R1700V is capable of Arbitrary Setting an Output Voltage based on Buck-boost (Inverting) Topology.
Integration of R1700V and R1580N realizes Flicker-free Operation in LED Lighting Applications.

ABSOLUTE MAXIMUM RATINGS
Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the permanent
damages and may degrade the lifetime and safety for both device and system using the device in the field. The
functional operation at or over these absolute maximum ratings is not assured.

RECOMMENDED OPERATING CONDITIONS
All of electronic equipment should be designed that the mounted semiconductor devices operate within the
recommended operating conditions. The semiconductor devices cannot operate normally over the recommended
operating conditions, even if when they are used over such conditions by momentary electronic noise or surge. And
the semiconductor devices may receive serious damage when they continue to operate over the recommended
operating conditions.
