[1] All specifications are typical unless noted. Ambient temperature = +25 degrees Celsius, Vin is
nominal (+48 Volts), output current is maximum rated nominal. Output capacitance is 1 μF ceramic
paralleled with 10 μF electrolytic. Input caps are 22 μF except HPH-3.3/70-D48 which is 100 μF input.
All caps are low ESR. These capacitors are necessary for our test equipment and may not be needed
in your application.
Testing must be kept short enough that the converter does not appreciably heat up during testing. For
extended testing, use plenty of airflow. See Derating Curves for temperature performance. All models
are stable and regulate within spec without external cacacitance.
[2] Input Ripple Current is tested and specified over a 5-20 MHz bandwidth and uses a special set of
external filters only for the Ripple Current specifications. Input filtering is Cin = 33 μF, Cbus = 220 μF,
Lbus = 12 μH except HPH-3.3/70-D48 is Cin = 100μF. Use capacitor rated voltages which are twice
the maximum expected voltage. Capacitors must accept high speed AC switching currents.
[3] Note that Maximum Current Derating Curves indicate an average current at nominal input voltage.
At higher temperatures and/or lower airflow, the converter will tolerate brief full current outputs if the
total RMS current over time does not exceed the Derating curve.
[4] Mean Time Before Failure (MTBF) is calculated using the Telcordia (Belcore) SR-332 Method 1,
Case 3, ground fixed conditions. TPCBOARD = +25 °C., full output load, natural air convection.
[5] The output may be shorted to ground indefinitely with no damage.
6] The On/Off Control is normally driven from a switch or relay. An open collector/open drain transistor
may be used in saturation and cut-off (pinch-off) modes. External logic may also be used if voltage
levels are fully compliant to the specifications.
[7] Regulation specifications describe the deviation as the input line voltage or output load current is
varied from a nominal midpoint value to either extreme.
[8] Do not exceed maximum power ratings, Sense limits or output overvoltage when adjusting output
trim values.
[9] At zero output current, Vout may contain components which slightly exceed the ripple and noise
specifications.
[10] Output overload protection is non-latching. When the output overload is removed, the output will
automatically recover.
[11] Because of the high currents, wire the appropriate input, output and common pins in parallel
groups. Be sure to use adequate PC board etch. If not sufficient, install additional discrete wiring. If
wiring is not sufficient, the Sense feedback may attempt to drive the outputs beyond ratings.
[12] The converter will shut off if the input falls below the undervoltage threshold. It will not restart
until the input exceeds the Input Start Up Voltage.
[13] Please refer to the separate output capacitive load application note from Murata Power Solutions.
[14] Output noise may be further reduced by installing an external filter. See the Application Notes.
[15] To avoid damage or unplanned shutdown, avoid sinking reverse output current.
[16] To protect against accidental input voltage polarity reversal, install a fuse in series with +Vin. See
Fusing information.
