●Description of Blocks

( 1 ) Start circuit (VH Pin : 8pin)

This IC built in the Start up circuit (tolerates 650V). It enables to be low standby mode electricity and high speed starting.

Figure 6. Start time( reference value)

* Start up current flows from the DRAIN pin

ex) Consumption power of start up circuit only when the Vac=100V

PVH＝100V*√2*10uA=1.41mW

ex) Consumption power of start up circuit only when the Vac=240V

PVH＝240V*√2*10uA=3.38mW
