Complies with ETS 300 386-1
The CXE15 is a new high efficiency open
protection features are included as
frame isolated 15 Watt converter series in
standard. With full international safety
an industry standard footprint. The first
approval including EN60950 and
four models in the series feature an input
cUL1950, the CXE15 reduces compliance
voltage range of 33 to 75VDC and are
costs and time to market.
available in output voltages of 5V, 3.3V,
2.5V and 1.8V. The output voltage on
each model is adjustable from 90% to
110% of the nominal value. Typical
efficiencies for the models are 87% for the
5V, 86% for the 3.3V, 85% for the 2.5V
and 83% for the 1.8V version. The CXE15
series also has a remote on/off capability,
with active 'HI' or active 'LO' logic options
available. Overcurrent and overvoltage

Note 1
Hot spot temperature is defined as the highest temperature
measured at any one of the specified hotspot checkpoints.
See Figure 46: Hotspot temperature check points.
Note 2
The control pin is referenced to Vin-.
Note 3
The CXE15 is supplied as standard with active high logic.
Control input pulled low: Unit disabled.
Control input left open: Unit enabled.
Figure 46: Hot Spot Location on all Models
Note 4
Thermal reference set up: Unit mounted on an edge card test
board 215mm x 115mm. Test board mounted vertically. For test
details and recommended set-up see Application Note 116.
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.
