Power Factor Correction Controller IC
Description
R2A20115 is a power-factor correction (PFC) controller IC, which employs continuous conduction mode as PFC
control mode. Various kinds of functions such as constant power limit, overvoltage detection, overcurrent detection,
soft start function, feedback-loop open detection, and the function holding its operation through momentary outage
(PFC hold function) are incorporated in a single chip. These functions reduce external circuitry.
The constant power limit function significantly reduces "coil vibration", which is caused by the operation of a
conventional overcurrent detection circuit when the system is overloaded.
The PFC hold function enables quick recovery by keeping PFC operation active for a certain duration (hold time)
during momentary outage/power failure. The hold time can be adjusted by an external capacitor.
This IC provides the separated pin used for detecting overcurrent, so that, the preset current value range for overcurrent
detection becomes wider than before.
The shutdown function with latch mode is also implemented.
A soft-start control pin is provided for the easy adjustment of soft-start operation.
And also the dynamic over voltage protection function integrated in this IC reduces overshooting of the output voltage,
which might occur for the duration of startup, recovery after momentary power failure and just after a sudden variation
of a load.
