NOTES:
A. IDSS is the worse case off state leakage specification at 805 of BVDSS 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 205 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 205 at high line input 26ꢀ VAC.
E. LinkZero-LP shuts down if current into BYPASS pin reaches ISD at BPSHUNT voltage.
