Figure 11. Recommended Circuit Board Layout for LinkSwitch using P Package.
LinkSwitch
has a minimum leading edge blanking time of
200 ns to prevent premature termination of the on-cycle.
Verify that the leading edge current spike event is below
current limit at the end of the 200 ns blanking period.
3. Thermal check – At peak output power, minimum input
voltage and maximum ambient temperature, verify that the
temperature specifications are not exceeded for
LinkSwitch
,
transformer, output diode and output capacitors. Enough
thermal margin should be allowed for part-to-part variation
of the R
of
LinkSwitch
as specified in the data sheet.
Under low line, peak power, a maximum
LinkSwitch
SOURCE pin temperature of 100
°
C is recommended to
allow for these variations.
4. Centered output characteristic – Using a transformer with
nominal primary inductance and at an input voltage midway
between low and high line, verify that the peak power point
occurs at the desired nominal output current, with the correct
output voltage. If this does not occur then the design should
be refined to ensure the overall tolerance limits are met.
