5 / 12 page STK416-090-E No. A1621-5/12 Recommended External Components Parts Location Recommended Value Circuit Purpose Above Recommended Value Below Recommended Value R01, R02 1.5k Ω Current for supply switch circuit (comparator) is determined. VH holding frequency range becomes large. VH holding frequency range becomes narrow. R03, R04 100 Ω/1W Resistance for ripple filter. (Fuse resistance is recommended. Ripple filter is constituted with C05, C06.) - Short-through current may increase at high frequency. R05, R06, R07 56k Ω Input impedance is determined. Output neutral voltage (VN) shift. (It is referred that R05=R18, R06=R19, R07=R20) R08, R09, R10 4.7 Ω/1W Resistance for oscillation prevention. - - R11, R12, R13 4.7 Ω Noise absorption resistance. - - R14, R15, R16 560 Ω Voltage gain (VG) is determined with R18, R19, R20. (As for VG, it is desirable to set up by R14, R15, R16.) It may oscillate. (VG <40dB) With especially no problem R18, R19, R20 56k Ω Voltage gain (VG) is determined with R14, R15, R16 - - R21, R22, R23 1k Ω Resistance for input filters. - - R24, R26, R28 0.22 Ω ±10%, 5W Output emitter resistor (Metal-plate Resistor is recommended.) Decrease of maximum output power It may cause thrmal runaway R30 Note*6 Select restriction resistance, for the impression voltage of ‘#17 (stand-by) pin’ must not exceed the maximum rating. C01, C02 100 μF/100V Capacitor for oscillation prevention. •Locate near the HIC as much as possible. •Power supply impedance is lowered and stable operation of the IC is carried out. (Electrolytic capacitor is recommended.) - - C03, C04 100 μF/50V Capacitor for oscillation prevention. •Locate near the HIC as much as possible. •Power supply impedance is lowered and stable operation of the IC is carried out. (Electrolytic capacitor is recommended.) - - C05, C06 100 μF/100V Decoupling capacitor •The ripple ingredient mixed in an input side is removed from a power supply line. (Ripple filter is constituted with R03, R04.) The change in the ripple ingredient mixed in an input side from a power supply line C07, C08, C09 3pF Capacitor for oscillation prevention. It may oscillate. C10, C11, C12 0.1 μF Capacitor for oscillation prevention. It may oscillate. C13, C14, C15 22 μF/10V Negative feedback capacitor. •The cutoff frequency of a low cycle changes. (fL=1/(2π•C13•R14)) The voltage gain (VG) of low frequency is extended. However, the pop noise at the time of a power supply injection also becomes large. The voltage gain (VG) of low frequency decreases. C16, C17, C18 2.2 μF/50V Input coupling capacitor (for DC current prevention.) - - C19, C20, C21 470pF Input filter capacitor •A high frequency noise is reduced with the filter constituted by R21, R22, R23. - - C22, C23, C24 100pF Capacitor for oscillation prevention. It may oscillate. D01, D02 15V Decide offset voltage for supply voltage ciecuit. Decrease distortion at supply voltage shift Increase distortion at supply voltage shift D03, D04 3A/60V Adverse current prevention diode (FRD is recommended) - - L01, L02, L03 3 μH Coil for oscillation prevention. With especially no problem It may oscillate. |
