Functional Description Applications This family of 10W DC/DC converters is specifically designed
for telecommunications applications including xDSL remote
power feed. These modules accept wide input voltage ranges
with nominal inputs of 24, 48 and 120Vdc. Outputs can be single
or dual and can be set as two independent adjustable outputs
from 5Vdc to 120Vdc. Additional features include total input to
output isolation, short circuit and thermal protection, soft start,
adjustable outputs, hot pluggability and efficiency up to 84%.
Key Features
• Efficiency up to 84%
• Input to output isolation
• Soft start
• Hot pluggable
• Short circuit and thermal protection
• Adjustable outputs
• 50µA off-state current
• Wide input voltage range (2:1)

Model Selection Guide
The maximum input current at any given input range measured at minimum input voltage is given as 1.6*INOMINAL. Nominal input current is the
typical value measured at the input of the converter under full-load room temperature and nominal input voltage (24, 48 and 120Vdc).

The RC input filter utilizes the RON of the series MOSFET transistor which is part of the hot pluggable circuit. The benefits of this RC
filters are the reduction of inrush current by approximately 27dB and reflected ripple attenuation by 8dB. The penalty for the hot
pluggability and the RC filter is 1% to 2% reduction of the converter ’s efficiency. See Figures 4 and 5.
