Sample Application Circuit
Description of External Components
C1,C8: Bootstrap capacitors
These capacitors affect low-region output; if the capacitor value is reduced, the low-region output decreases. Therefore,
47 F or more is desirable.
C2,C6: Output capacitors
If the capacitor value is reduced, low-region roll-off frequency fL and low-region Po worsen.
C3,C7: Oscillation blocking capacitors
Mylar capacitor, which is excellent in temperature characteristics and frequency characteristics is used.
C4:
Power supply capacitor
The capacitor values depends on the power supply line loads (motor, and the like.) and transformer ripple component.
1000 F to 2200 F is recommended.
C5:
Standby capacitor
Pop noise reduction capacitor
C9,C11: Feedback capacitors
In addition to affecting low-region roll-off frequency fL, if the capacitor value is increased, the start-up time is extended.
C10:
Decoupling capacitor
This capacitor absorbs power supply ripples; 220 F is recommended.
R1,R2: Oscillation blocking resistors
The resistor value may be varied 3.3
to 1.0 .
Mylar capacitor
Unit (resistance:
, capacitance:F)
To large signal GND
Mylar capacitor
C + R can be added to the negative side of the output capacitor.
However, this is true only for a Sanyo-recommended board; for a set board, artwork must also be
considered.
