Fairchild PFC/PWM Controller Combination
Fairchild's
highly integrated
PFC/PWM Controller Combination ICs
are specifically designed for power supplies that consist of boost
PFC
and
PWM
. These
PFC/PWM Controller Combination ICs
require very few external components to achieve protection/compensation.
Fairchild's PFC/PWM Controller Combination ICs
can be used in either current or voltage mode. In voltage mode, feed-forward from the
PFC
output bus can reduce the secondary output ripple. These
PFC/PWM Controller Combination ICs
offer features which include low operating current, innovative switching-charge multiplier divider, average-current mode for input-current shaping,
PFC
over-voltage and under-voltage protection,
PFC
feedback open-loop protection, power-on sequence control and soft start and brownout protection.
