FSD210B Advantages
• Gradually increasing current limit
during soft-start further reduces peak
current and voltage stresses
• Eliminates external components used
for soft-start in most applications
• Reduces or eliminates output
overshoot
• Smaller transformer
• Reduced conducted EMI
• Improves light load efficiency
• Reduces power consumption at no-
load
• Transformer audible noise reduction
• Greater immunity to arcing provoked
by dust, debris and other contami-
nants
