Improved efficiency by valley switching
Reduced EMI noise
Reduce EMI noise by two ways
Improved standby power by valley switch-
ing also in burst-mode
Because the current peak during burst
operation is dependent on V
to solve audible noise
Improved reliability through precise abnor-
mal over-current protection
FSQ-Series Advantages
