Over Temperature Protection
The OTP is achieved by thermistor U1 and the threshold is set at 120C in non-latch mode; the hottest component
Q5 reaches 130C with 100LFM air flow correspondingly. It will restart automatically when the temperature falls
down to 100C. The protecting point will be varied a little under different conditions (air flow, ambient temperature,
input voltage, load...).
