IP3002 / I3002
Power Factor Correction
DESCRIPTIONS
It is adaptable to a discontinuous mode of operation
that the IP3002 is PFC (Power Factor Correction)
controller for the high density switching mode power
supply and electronic ballast systems. The bulky
external components are eliminated in the internal
start-up circuits, though it is taken in independent
boost converter operation. What is more, instead of
the external components, the low pass filter is
mounted in internal current sense block. Internal
clamping of the error amplifier and multiplier output
improve turn on overshoot characteristics and current
limiting. The one of features is able to prevent abnor-
mal condition, open lamp & over voltage.
