Bipolar IC
For Power Factor Correction
s Description
FA5331P(M) and FA5332P(M) are control ICs for a power
factor correction system. These ICs use the average current
control system to ensure stable operation. With this system, a
power factor of 99% or better can be achieved.
FA5331P(M) is a 1st generation IC and FA5332P(M) is 2nd
generation IC which light-load characteristics are improved.
