Resistance for Ripple filter. (Fuse resistance is recommended.
Ripple filter is constituted with C03, C23.)
Resistance for input filters.
Input impedance is determined.
Voltage Gain (VG) is determined with R11, R12, R13
Voltage Gain (VG) is determined with R8, R9, R10
Resistance for oscillation prevention.
Resistance for oscillation prevention.
This resistance is used as detection resistance of the protection
circuit application.
Select Restriction resistance, for the impression voltage of ‘#17 (Stand-By) pin’ must not exceed the maximum
rating.
Capacitor for oscillation prevention.
• Locate near the HIC as much as possible.
• Power supply impedance is lowered and stable operation of
Decoupling capacitor
• The Ripple ingredient mixed in an input side Is removed from a
Input coupling capacitor.(for DC current prevention.)
Input filter capacitor
• A high frequency noise is reduced with the filter constituted by
Capacitor for oscillation prevention.
Negative feedback capacitor.
The cutoff frequency of a low cycle changes.
Capacitor for oscillation prevention.
Capacitor for oscillation prevention.
Coil for oscillation prevention.
(As for VG, it is desirable to set up by R11, R12, R13)

Circuit purpose
Short-through current
may decrease at
high frequency.
Output neutral voltage(VN) shift.
(It is referred that R05=R08, R06=R09)
It may oscillate.
(Vg < 30dB)
Decrease of
Maximum output
Power
The change in the Ripple ingredient mixed in
an input side from a power supply line
It may oscillate.
The voltage gain (VG)
of low frequency is
extended. However,
the pop noise at the
time of a power
supply injection also
becomes large.
It may oscillate.
It may oscillate.
