Description of External parts
C1, C2
: Input capacitors. A value of 1.0
F is recommended for capacitors. Note that the low-frequency area
characteristics can be adjusted by changing fL.
C3
: Ripple filter capacitor. A value of 47
F is recommended for capacitors. Decreasing the capacitance value
excessively or removing this capacitor causes ripple to occur. However, increasing the capacitance value
does not always cause ripple to reduced. Decreasing the capacitance value makes the starting time earlier.
C4
: Power capacitor.
C5, C6
: Output capacitors. A value of 470
F is recommended for capacitors.
C7, C8
: Oscillation blocking capacitor. Use a polyester film capacitor that is good in high frequency response and
temperature characteristic.
C9, C10
: Feedback capacitor. A value of 47
F is recommended for capacitors. Decreasing the capacitance value
lowers the low frequency response. Increasing the capacitance value makes the starting time later.
R1, R2
: Resistor connected in series with oscillation blocking capacitor. Prevents phase shift attributable to the
oscillation blocking capacitor so that oscillation is hard to occur.
R3
: Standby switch current limiting resistor. A value of 10k
is recommended for resistance (when the applied
voltage for the standby switch is 3V to 10V). This resistor cannot be removed.
