- Resistors are in ohms, 1/8W unless otherwise noted.
Special note :
Most semiconductor devices are electrostatically sensitive and therefore require the special handling techniques
described under the “electrostatically sensitive (ES) devices” section of this service manual.
Note :
Do not use the part number shown on this drawing for ordering. The correct part number is shown in the parts list
(may be slightly different or amended since this drawing was prepared).
Important safety notices :
Components identified with the mark
components. Use only the same type.

7-2-1 About S.M.P.S (Ringing Choke Converter Method)
(b) SNUBBER Circuit :
RIS02, RIS03, CIS08, CIS07, DIS05
Terms
1) 1st : Common power input to 1st winding.
2) 2nd : Circuit followings output winding of transformer.
3) f (Frequency) : Switching frequency (T : Switching cycle)
4) Duty : (Ton/T) x 100
1) Prevent residual high voltage at the terminals of
switch during switch off/Suppress noise.
High inverted power occurs at switch off,
because of the 1st winding of transformer :
(V=-L1 xdi/dt. L1 : Leakage Induction)
A very high residual voltage exist on both terminals
of ICIS01 because dt is a very short.
7-2-2 Circuit description [FLY-Back RCC(Ringing Choke Converter)] Control
(a) AC Power Rectification/Smoothing Terminal
1) A01~04 : Convert AC power to DC (Wave rectification).
2) CIS01 : Smooth the voltage converted to DC.
3) LIS01, LISO2, CIS04, CIS05 : Noise removal at power input/output.
4) RIS04 : Rush current limit resistance at the momemt of power cord insertion.
· Without PLRU1, the bridge diode might be damaged as the rush current increases.
2) SNUBBER circuit protects ICIS01 from damage
through leakage voltage suppression by RC,
(Charges the leakage voltage to DIS05 and CIS08
and discharges to RIS03, RIS02).
3) CIS07 : For noise removal
Fig. 7-2
(c) IC1S01 Vcc circuit
1) ICIS01, RIS05, RIS07,RIS08 : ICIS01 driving resistance (ICIS01 works through driving resistance at power
cord in)
2) ICIS01 Vcc : RIS05, RIS07, RIS08
q Use the output of transformer as Vcc,because the current starts to flow into transformer while ICIS01 is
active
w Rectify to DIS07 and smooth to CIS09.
e Use the output of transformer as ICIS01 Vcc : The loads are different before and after ICIS01 driving.
(Vcc of ICIS01 decreases below OFF voltage , using only the resistance dut to lode increase after ICIS01
driving.)
