Features and Options
On/Off Control
The input-side, remote On/Off Control function (pin 4) can be ordered to operate
with either polarity:
Standard models are equipped with Positive-polarity (no part-number sufx)
and these devices are enabled when pin 4 is left open (or is pulled high, ap-
plying to +15V with respect to –Input, pin 2) as per Figure 4. Positive-polarity
devices are disabled when pin 4 is pulled low (0 to 0.8V with respect to –Input).
Optional Negative-polarity devices ("N" sufx) are off when pin 4 is left
open (or pulled high, applying +3.5V to +15V), and on when pin 4 is pulled low
(0 to 0.8V) with respect to –VIN as shown in Figure 5.
Dynamic control of the remote on/off function is best accomplished with a
mechanical relay or an open-collector/open-drain drive circuit (optically iso-
lated if appropriate). The drive circuit should be able to sink appropriate current
(see Performance Specs) when activated and withstand appropriate voltage
when deactivated. Applying an external voltage to pin 4 when no input power is
applied to the converter can cause permanent damage to the converter.
Trimming Output Voltage
UHE converters have a trim capability (pin 9) that allows users to adjust the
output voltages ±5% of VOUT (±10% for T models). Adjustments to the output
voltages can be accomplished via a trim pot (Figure 6) or a single xed resistor
as shown in Figures 7 and 8. A single xed resistor can increase or decrease
the output voltage depending on its connection. The resistor should be located
close to the converter and have a TCR less than 100ppm/°C to minimize
sensitivity to changes in temperature. If the trim function is not used, leave the
trim pin oating.
A single resistor connected from the Trim (pin 9) to the +Output (pin 6), or
+Sense where applicable, will decrease the output voltage for all models with
the exception of the 1.2V models, which will increase the output voltage in this
conguration. A resistor connected from the Trim (pin 9) to the –Output (pin 7),
or –Sense where applicable, will increase the output voltage for all models with
the exception of the 1.2V models, which will decrease the output voltage in this
conguration.
Soldering Guidelines
Murata Power Solutions recommends the specications below when installing these
converters. These specications vary depending on the solder type. Exceeding these
specications may cause damage to the product. Be cautious when there is high atmo-
spheric humidity. Your production environment may differ; therefore please thoroughly
review these guidelines with your process engineers.
