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.
