Quick Design Checklist
Maximum Drain Voltage
Verify that the peak V
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 that
stated for the 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 LinkSwitch-PH,
transformer, output diodes, output capacitors and drain clamp
components.
