Quick Design Checklist
Maximum Drain Voltage
Verify that the peak V
does not exceed 670 V under all
DS
operating conditions including start-up and fault conditions.
Maximum Drain Current
Measure the peak drain current under all operation conditions
including start-up and fault conditions. Look for signs of
transformer saturation (usually occurs at highest operating
ambient temperatures). Verify that the peak current is less than
the stated Absolute Maximum Rating in the data sheet.
Thermal Check
At maximum output power, both minimum and maximum line
voltage and ambient temperature; verify that temperature
specifications are not exceeded for the LYTSwitch, transformer,
output diodes, output capacitors and drain clamp components.
