lnk354 Power Integrations, Inc., lnk354 Datasheet - Page 9

• Manufacturer Part Number: lnk354
• Description: Enhanced, Energy Ef?cient, Low Power Off-line Switcher Ic
• 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 Figure 14 for BYPASS pin start-up 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 13.
F. This parameter is guaranteed by design.
G. This parameter is derived from characterization.
H. Auto-restart on time has the same temperature characteristics as the oscillator (inversely proportional to
