Continuous conduction mode (CCM) PFC controller with high voltage startup

ECCN USEAR99
ECCN EUNEC
Packing TypeTube
RoHs compliantEcopack3
GradeIndustrial
Package NameSO-8

The L4985 is a peak current-mode PFC controller for boost converter with a proprietary multiplier “emulator” which in addition to the innovative THD optimizers guarantee very low Total Harmonic Distortion (THD) performance in all operating conditions. The device comes in a pin SO package and...
