Descriptions
The KA7526 provides simple and high performance active
power factor correction. KA7526 is optimized for electronic
ballast and low power, high density power supplies requiring
a minimum board area, reduced component count and low
power dissipation. Addition of internal R/C filter eliminates
the need for an external R/C filter. Internal clamping of the
error amplifier and multiplier outputs improves turn on over-
shoot characteristics and current limiting. Special circuitry
has also been added to prevent no load runaway conditions.
The output drive clamping circuit limits overshoot of the
power MOSFET gate drive Independent of supply voltage,
so that it greatly enhance the system reliability.
