DC/DC CONVERTERS 40W High Efficiency DC/DC Converters
1
• High efficiency topology, 91% typical at 5V
• Approved to EN60950, UL1950, CSA C22.2 No. 234/950
• Operating ambient temperature of -40°C to +70°C
(natural convection)
• Complies with ETS 300 019-1-3/2-3
• Complies with ETS 300 132-2 input voltage and current
requirements
• Fully compliant with ETS 300 386-1
The EXA40 Series, comprising 8 different models is targeted specifically at the
telecommunications, industrial electronics, mobile Telecommunications and distributed
power markets. The series offers two wide input voltage ranges of 18-36VDC and
36-75VDC. Typical efficiencies are 91% for the 5V output, 88% for the 3.3V, 86%
for the 2.75V and 84% for the 1.8V. The series has been designed primarily for
Telecommunications applications and complies with ETS 300 386-1 immunity and
emission standards for high priority of service class. In addition the series complies
with ETS 300 019-1-3 environmental standards (all classes) including shock, vibration,
humidity and thermal performance. A high level of reliability has been designed into all
models through the extensive use of conservative derating criteria. Remote enable and
overtemperature shutdown are included as standard while true latching OVP is
available as an option.
All specifications are typical at nominal input, full load at 25°C unless otherwise stated
