Complies with ETS 300 386-1
The EXB30 is a new high efficiency single
output open frame isolated 30 Watt
converter series in an industry standard
footprint. The first five models in the series
feature a 2:1 input voltage range of 36 to
75VDC and are available in output voltages
of 12V, 5V, 3.3V, 2.5V and 2V. The output
voltage is trimmable from 80 to 110%
except the 12V model which has a wider
trim range of 60 to 110%. The sub 5V
models have an output current rating of 8A.
Typical efficiencies for the models are 92%
for the 5V, 90% for the 3.3V and 12V, 88%
for the 2.5V and 87% for the 2V version.
The EXB30 series offers remote on/off and
remote sense compensation to correct for
voltage drops at the load. Overcurrent,
overvoltage and overtemperature protection
features are included as standard.
With full international safety approval
including EN60950 and cUL1950, the
EXB30 reduces compliance costs and time
to market.
The series complies with ETS 300 386-1
EMC requirements, ETS 300 132-2
concerning the power supply interface at
the input to telecommunications equipment
and ETS 300 019-1-3 concerning
environmental conditions. The EXB30 single
is primarily targeted at the networking,
telecom and wireless markets.

Note 1
Hot spot temperature is defined as the highest temperature
measured at any one of the specified temperature hotspot
checkpoints. See Figure 8: Hotspot temperature check points.
Note 2
The control pin is referenced to Vin-.
Note 3
The EXB30 is supplied as standard with active high logic.
Control input pulled low: unit disabled.
Control input floating: unit enabled.
The unit can be supplied with active low logic.
Note 4
The outputs of these converters should not be connected in
parallel.
Note 5
Thermal reference set up: Unit mounted centrally on a 200mm x
240 mm testboard. Testboard is mounted vertically in a fully
enclosed 300mm x 300mm x 300mm testbox. Ambient
temperature measur ed at the bottom of the textbox. Altitude sea
level.
Note 6
12V model is rated at 30W and 36W for maximum ambient
temperatures of 85˚C and 80˚C respectively.
CAUTION: Hazardous internal voltages and high temperatures.
Ensure that unit is accessible only to trained personnel. The user
must provide the recommended fusing in order to comply with
safety approvals.
