■ Features
● AC input detecting function
● By connecting SO terminal, it is able to select functions as below:
   1) Boot up and stop operation according to AC input or output 
      (short-circuit SO teminal to VDD terminal)
   2) Signal output form SO terminal when AC input is low and transmit to
      the secondary side (connect an external element to SO terminal)
● Built-in jitter function
● Power consumption 30 mW or less at a no load is achieved
● Protection function is built into.
   (over load protection, over voltage protection, over heat protection)

■ Applications
● Thin TVs and othes
