１ - Recommended operating conditions
IRIS-F6454R
Absolute Maximum Ratings (Ta=25ºC)
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters are
absolute voltages referenced to terminals stated, all currents are defined positive into any lead. The thermal resistance and power
dissipation ratings are measured under board mounted and still air conditions.
Time for input of quasi resonant signals
For the quasi resonant signal inputted to O.C.P/F.B Pin at the time
of quasi resonant operation, the signal shall be wider than T
*1 Refer to MOS FET A.S.O curve
*2 MOS FET Tch-EAS curve
*3 Refer to MOS FET Ta-PD1 curve
*4 Refer to TF-PD2 curve for Control IC (See page 5)
*5 Maximum switching current.

The maximum switching current is the Drain current determined by the drive voltage of the IC and
threshold voltage (Vth) of MOS FET. Therefore, in the event that voltage drop occurs between Pin 2 and
Pin 5 due to patterning, the maximum switching current decreases as shown by V
Accordingly please use this device within the decrease value, referring to the derating curve of the
maximum switching current.
