Output Over Voltage Protection:
microprocessor and a parallel regulation path with an
independent reference. If the output voltage exceeds
the over-voltage specification, the microprocessor will
latch the converter off. To turn the converter on requires
either cycling the ON/OFF pin or power to the
converter. This advanced feature prevents the converter
from damaging the load if there is a converter failure or
application error. If non-latching is required, consult
factory.
Thermal Shutdown:
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:

design experience but we understand that customers
often have their own requirements.
Remote Sense:
sense pins connect to the power output pins. Total sense
compensation should not exceed 0.4V or 10% of Vout,
whichever is greater.
Safety:
these safety requirements.

Trim:
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. See diagram below.
