STACF01ATR

Active clamp flyback controller

ECCN USEAR99
ECCN EUNEC
Packing TypeTape And Reel
RoHs compliantEcopack2
GradeIndustrial
Package NameQFN5X5X1.2 - 23L MULTIPLE PITCH

The STACF01A and STACF01B ICs drive and control active clamp flyback converters with non-complementary driving of the active clamp (high-side, HS) switch. It is specifically intended for high performance AC-DC adapters with GaN HEMTS rated up to 100 W and beyond, which are aimed at high efficiency...
