Notes
Unless otherwise noted, all specications apply over the input voltage range, full temperature
range, nominal output voltage and full output load. General conditions are near sea level altitude,
no base plate installed and natural convection airow unless otherwise specied. All models are
tested and specied with external parallel 1 μF and 10 μF multi-layer ceramic output capacitors.
No external input capacitor is used (see Application Notes). All capacitors are low-ESR types wired
close to the converter. These capacitors are necessary for our test equipment and may not be
needed in the user’s application.
Input (back) ripple current is tested and specied over 5 Hz to 20 MHz bandwidth. Input ltering is
Cin = 33 μF, Cbus = 220μF and Lbus = 4.7 μH.
All models are stable and regulate to specication under no load.
The Remote On/Off Control is referred to -Vin.
Regulation specications describe the output voltage changes as the line voltage or load current
is varied from its nominal or midpoint value to either extreme. The load step is ±25% of full load
current.
Output Ripple and Noise is measured with Cout = 1μF MLCC paralleled with 10μF tantalum, 20
MHz oscilloscope bandwidth and full resistive load.
The Sense and Trim pins are removed for the “X” model option.
NOTICE—Please use only this customer data sheet as product documentation when laying out your
printed circuit boards and applying this product into your application. Do NOT use other materials as
ofcial documentation such as advertisements, product announcements, or website graphics.
We strive to have all technical data in this customer data sheet highly accurate and complete. This cus-
tomer data sheet is revision-controlled and dated. The latest customer data sheet revision is normally
on our website (www.murata-ps.com) for products which are fully released to Manufacturing. Please be
especially careful using any data sheets labeled “Preliminary” since data may change without notice.
The pinout (Pxx) and case (Cxx) designations (typically P65 or C59) refer to a generic family of
closely related information. It may not be a single pinout or unique case outline. Please be aware
of small details (such as Sense pins, Power Good pins, etc.) or slightly different dimensions
(baseplates, heat sinks, etc.) which may affect your application and PC board layouts. Study the
Mechanical Outline drawings, Input/Output Connection table and all footnotes very carefully.
Please contact Murata Power Solutions if you have any questions.
Minimum efciency applies over all input voltages, the full operating temperature range and full
load.
