The CXE15 is a new high efficiency open

frame isolated 15 Watt converter series in

an industry standard footprint. The first

four models in the series feature an input

voltage range of 33 to 75VDC and are

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

protection features are included as

standard. With full international safety

approval including EN60950 and

cUL1950, the CXE15 reduces compliance

costs and time to market.

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.

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.
