10．Application circuit example
Caution）
AN-071E Rev.1.2
April-2011
1) This application circuit example shows typical directions for use of this IC for reference and does not guarantee the
operation and characteristics.
2) VH Pin is connected to near by diode bridge (DS1) to avoid VH Pin’s surge voltage it happens by change of startup
3) Please connect the diode and resistance with the series between the bulk capacitor or the rectified AC line so that VH
AC90 to
264V
current when startup circuit repeats on-off operating.
Pin must not become a negative voltage.
