Protection and Control
Thermal Shutdown
The printed circuit board temperature is measured using a
semiconductor sensor. If the maximum rated temperature
is exceeded, the converter is latched off. To re-enable the
converter requires cycling the ON/OFF pin or power to the
converter. If non-latching is required, consult factory.
Control Options
As the behavior of the circuit is determined by firmware in the
microcontroller, specific requirements, such as:
• non-latching thermal protection
• custom valid input voltage range
• controlled delay from initiating an ON/OFF signal for
power sequencing
can be accomplished with no change to hardware. The
standard behavior was chosen based on system design
experience, but customers may have their own requirements.
Please contact Bel Power for any special needs.
Remote Sense
The output voltage is regulated at the point where the
sense pins connect to the power output pins. Total sense
compensation should not exceed 0.4V or 10% of Vout,
whichever is greater.

Safety
An external input fuse must always be used to meet these
safety requirements.

Trim
To trim the output voltage higher, connect the required trim
resistor from the Trim pin to the +Sense pin. To trim the output
voltage lower, connect the required trim resistor from the Trim
pin to the –Sense pin.
