value
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.
(As for VG, it is desirable to set up by R11, R12, R13.)
Noise absorption resistance.
Resistance for oscillation prevention.
Output emitter resistor
(Metal-plate resistor is recommended.)
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
Decoupling capacitor
• The ripple ingredient mixed in an input side is removed
Input coupling capacitor. (for DC current prevention.)
Input filter capacitor
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.
• A high frequency noise is reduced with the filter
operation of the IC is carried out. (Electrolytic capacitor
is recommended.)
constituted by R02, R03, R04.
(f L =1/(2π ⋅ C13 ⋅ R11))
from a power supply line. (Ripple filter is constituted
with R03, R04.)
Circuit purpose
STK433-290-E
Output neutral voltage (VN) shift.
(It is referred that R05=R08, R06=R09, R07=R10)
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.
