• Manufacturer Part Number: pks603
• Description: Enhanced, Energy-eficient, Off-line Switcher Ic With Super Peak Power Performance
• Manufacturer: Power Integrations, Inc.

NOTES:
A. Total current consumption is the sum of I
B. Since the output MOSFET is switching, it is difficult to isolate the switching current from the supply current at the
C. See Typical Performance Characteristics section for BYPASS pin startup charging waveform.
D. BYPASS pin is externally supplied (bias winding).
E. For current limit at other di/dt values, refer to Figure 25.
F. This parameter is derived from characterization.
G. This parameter is derived from the change in current limit measured at 1X and 4X of the di/dt shown in the I

reduces its oscillator clock frequency to prevent excessive drain currents. If excessive drain currents are still
