FUNCTIONAL SPECIFICATIONS, UEE-3.3/15-D48 (CONT.)

Notes

➀ Unless otherwise noted, all specifications 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 airflow.

All models are tested and specified 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.

➁ Input (back) ripple current is tested and specified over 5 Hz to 20 MHz bandwidth. Input filtering is

Cbus=220 μF, Cin=33 μF and Lbus=12 μH.

➂ All models are stable and regulate to specification under no load.

➃ The Remote On/Off Control is referred to -Vin. For external transistor control, use open collector

logic or equivalent.

➄ 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

official 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

Outline drawings, Input/Output Connection table and all footnotes very carefully. Please contact

Murata Power Solutions if you have any questions.
