Notes
? Unless otherwise noted, all speci?cations are at nominal input voltage, nominal output voltage and
full load.
General conditions are +25? Celsius ambient temperature, near sea level altitude, natural convec-
tion air?ow.
All models are tested and speci?ed with external parallel 1 μF and 10 μF multi-layer ceramic
output capacitors.
No external input capacitor is used. 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 ap-
plication.
? Input (back) ripple current is tested and speci?ed over 5 Hz to 20 MHz bandwidth. Input ?ltering is
Cbus=220 μF, Cin=33 μF and Lbus=12 μH.
? All models are stable and regulate to speci?cation under no load.
? The Remote On/Off Control is referred to -Vin. For external transistor control, use open collector
RoHS-6
? 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
of?cial 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 P32 or C56) 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 which may affect your application and PC board layouts. Study the Mechanical
