Overview
FA5331P(M)/FA5332P(M) FA5331P(M)/FA5332P(M) 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.
