Thermal Derating Curve  
Maximum junction temperature of semiconductors derated to 120 degree C.  
AIR FLOW  
Bottom view  
Derating curve under 48V input  
The OTP is achieved by temperature sensor U10 and it is in non-latch mode when the hottest component Q12  
reaches 120°C with 200LFM air flow correspondingly. It will restart automatically when the temperature falls  
down to 105°C. The protecting point will be varied a little under different conditions (air flow, ambient temperature,  
input voltage, load...).

Over Current Protection  
To provide protection in a fault output overload condition, the module is equipped with internal current-limiting  
circuitry and can endure current limiting for a few mili-seconds. If the over current condition persists beyond a few  
milliseconds, the module will shut down into hiccup mode and restart once every 400mS. The module operates  
normally when the output current goes into specified range. The typical average output current is 4.8A during  
hiccup.
