Thermal Derating Curve (continued)

The OTP is achieved by thermistor R65 and it is in non-latch mode when the hottest component Q5 reaches

130°C with 100LFM air flow correspondingly. It will restart automatically when the temperature falls down to

110°C. The protecting point will be varied a little under different conditions (air flow, ambient temperature, input

voltage, load...).
