• Manufacturer Part Number: LNK362-364
• Description: Energy Effi cient, Low Power Off-Line Switcher IC
• Manufacturer: FERYSTER [FERYSTER Inductive Components Manufacturer]

NOTES:
A. Total current consumption is the sum of I
B Since the output MOSFET is switching, it is diffi cult to isolate the switching current from the supply current at the
C. See Typical Performance Characteristics section Figure 15 for BYPASS pin startup charging waveform.
D. This current is only intended to supply an optional optocoupler connected between the BYPASS and FEEDBACK
E. For current limit at other di/dt values, refer to Figure 14.
F. This parameter is guaranteed by design.
G. This parameter is derived from characterization.
H. Breakdown voltage may be checked against minimum BV
I. Auto-restart on time has the same temperature characteristics as the oscillator (inversely proportional to
