Nisshinbo R1700V Series PFC/LED Driver Controllers
Nisshinbo R1700V Power Factor Correction (PFC)/LED Driver Controllers are zero-voltage switching devices with a variable output voltage. These modules are ideal for improving the power factors of LED lighting and consumer appliances. The R1700V series offer an arbitrary setting of output voltage based on buck-boost (inverting) topology and operates at an input voltage range from 8V to 650V. Typical applications include LED lighting PFCs, flicker-free LED lighting, low-output voltage PFCs, and DC/DC converters. Nisshinbo R1700V Power Factor Correction (PFC)/LED Driver Controllers are available in an SSOP-16 package.Features
