5. Main Features and Functions
5.1 Operating Temperature Range
V-Infinity’s VPOL15A-5-SIP series converters highly efficient converter
design has resulted in its ability to operate over a wide ambient
temperature environment ( -40° C to 85°C). Due consideration must be
given to the de-rating curves when ascertaining maximum power
be drawn from the converter. The maximum power drawn is influenced
by a number of factors, such as:
5.2 Over-Temperature Protection (OTP)
The VPOL15A-5-SIP series converters are equipped with non-latching
over-temperature protection. A te mperature sensor monitors the
temperature of the hot spot (typically, top switch). If the temperature
exceeds a threshold of 120°C (typical) the converter will shut down,
disabling the output. When the temperature has decreased the
will automatically restart.
The over-temperature condition can be induced by a variety of
such as external overload condition or a system fan failure.
5.3 Output Voltage Adjustment
Section 7.9 describes in detail as to how to trim the output voltage
respect to its set point. The output voltage on all models is trimmable in
the range 0.9 – 3.63Vdc.
5.4 Safe Operating Area (SOA)
Figure 2 provides a graphical representation of the safe operating
(SOA) of the converter. This representation assumes ambient operating
conditions such as airflow are met as per thermal guidelines provided in
Sections 7.2 and 7.3.

5.6 Remote On/Off
The remote on/off input feature
to turn the converter on
standard. The VPOL15A-5-SIP series converters are turned on if the
remote on/off pin is high, or left open or floating. Setting the pin low will
turn the converter ‘Off’. The signal level of the remote on/off input is
defined with respect to ground. If not using the remote on/off pin, leave
the pin open (module will be on). The part number suffix “N” is Negative
remote on/off version. The unit is guaranteed off over the full temperature
range if this voltage level exceeds 2.8Vdc. The converters are turned on
