NOTES:
A. I_DSS is the worse case off state leakage specification at 80% of BV_DSS and maximum operating junction temperature.
B. This parameter is derived from characterization.
C. Output frequency specification applies to low line input voltage in the final application. The controller is designed to reduce output
frequency by approximately 20% at high line input voltages to balance low line and high line maximum output power.
D. The auto-restart on-time/off-time is increased by 20% at high line input 265 VAC.
E. LinkZero-LP shuts down if current into BYPASS pin reaches I_SD at BP_SHUNT voltage.
