L6566BTR

Multi-mode controller for SMPS

ECCN USEAR99
ECCN EUNEC
Packing TypeTape And Reel
RoHs compliantEcopack2
GradeIndustrial
Package NameSO-16

The L6566B is an extremely versatile current-mode primary controller ICs, specifically designed for high-performance offline flyback converters. It is also suited for single-stage single-switch input-current-shaping converters (single-stage PFC) for applications supposed to comply with EN61000-3-2...
