The Future of Analog IC Technology
DESCRIPTION
The MP44010 is a boundary conduction mode
PFC controller which can provide simple and
high performance active power factor correction
using minimum external components.
The output voltage is accurately regulated by a
high performance voltage mode amplifier with
an accurate internal voltage reference.
The precise adjustable output over-voltage
protection greatly enhances the system
reliability.
The on-chip R/C filter on the current sense pin
can eliminate the external R/C filter.
The extremely low start-up current, quiescent
current and the disable function can reduce the
power consumption and result in excellent
efficiency performance.
The MP44010 is available in SOIC8 and DIP
packages.
