5. Main Features and Functions
5.1 Operating Temperature Range
V-Infinity’s VPOL5A-5-SMT series converters highly efficient converter
design has resulted in its ability to operate over a wide ambient
temperature environment ( -40
given to the de-rating curves when ascertaining maximum power that can
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 VPOL5A-5-SMT 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 converter
will automatically restart.
The over-temperature condition can be induced by a variety of reasons
such as external overload condition or a system fan failure.
5.3 Output Voltage Adjustment
Section 7.8 describes in detail as to how to trim the output voltage with
respect to its set point. The output voltage on all models is trimmable in
the range 0.75 – 3.63 Vdc.
These can be effective heat sinks for the converter.
Input voltage range.
Output load current.
Air velocity (forced or natural convection).
Mounting orientation of converter PCB with respect to the Airflow.

5.4 Safe Operating Area (SOA)
Figure 2 provides a graphical representation of the Safe Operating Area
(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.
5.5 Over Current Protection
All different voltage models have a full continuous short-circuit protection.
The unit will auto recover once the short circuit is removed. To provide
protection in a fault condition, the unit is equipped with internal over-
current protection. The unit operates normally once the fault condition is
removed. The power module will supply up to 150% of rated current. In
the event of an over current converter will go into a hiccup mode
protection.
5.6 Remote On/Off
The remote on/off input feature of the converter allows external circuitry
to turn the converter ON or OFF. Active-high remote on/off is available
as standard. The VPOL5A-5-SMT 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 2.8 Vdc. The converters
are turned on If the on/off pin input is low or left open. The recommended
SMTremote on/off drive circuit as shown as figure 3, 4.
