Over Temperature Protection (OTP)
The DC/DC converters are protected from thermal overload by
an internal over temperature shutdown circuit.
When Tref as defined in thermal consideration section exceeds
125°C the DC/DC converter will shut down. The DC/DC
converter will make continuous attempts to start up (non
latching mode) We provide an optional variant of the product
with a latching OTP. Add suffix “LP” to the standard product
code to order the latching version. The latching OTP version
has a latching OVP as well.
If the OTP/OVP is latched the module can be put in operation
either by switching OFF and ON the input voltage or drive OFF
and ON the RC (Remote Control) pin.
Over Voltage Protection (OVP)
The DC/DC converters have output over voltage protection
that will shut down the DC/DC converter in over voltage
conditions. The DC/DC converter will make continuous
attempts to start up (non-latching mode) and resume normal
operation automatically after removal of the over voltage
condition.
Add suffix “LP” to the standard product code to order the
latching version. The latching OVP version has a latching OTP
as well.
If the OTP/OVP is latched the module can be put in operation
either by switching OFF and ON the input voltage or drive OFF
and ON the RC (Remote Control) pin.
Over Current Protection (OCP)
The DC/DC converters include current limiting circuitry for
protection at continuous overload.
The output voltage will decrease towards zero when the
output current exceeds max output current (max Io).
Under output short circuit, when the output current is in
excess of max output current (max Io), the DC/DC Converter
will enter a hiccup mode protection. The DC/DC converter will
resume normal operation after removal of the overload or
short circuit.
