FSQ-Series Advantages

Valley switching

operation

„ Improved efficiency by valley switching

„ Reduced EMI noise

Valley switching &

inherent frequency

modulation

„ Reduce EMI noise by two ways

„ Improved standby power by valley switch-

ing also in burst-mode

Advanced burst-mode „ Because the current peak during burst

operation is dependent on VFB, it is easier

to solve audible noise

AOCP

„ Improved reliability through precise abnor-

mal over-current protection
