Absolute maximums are stress ratings. Exposure of devices to greater than any of

any of these conditions may adversely affect long-term reliability. Proper operation

under conditions other than those listed in the Performance/Functional Specifications

Table is not implied nor recommended.

Specification Notes:

(1)

Specifications are typical at +25 °C, Vin=nominal (+5V), Vout=nominal (+3.3V), full load, external caps and

natural convection unless otherwise indicated. Extended tests at full power must supply substantial forced airflow.

All models are tested and specified with external 10μF ceramic output capacitors and a 22 μF external

input capacitor. All capacitors are low ESR types. These capacitors are necessary to accommodate our test

equipment and may not be required to achieve specified performance in your applications. However, Murata

Power Solutions recommends installation of these capacitors. All models are stable and regulate within

spec under no-load conditions.

(2)

Input Back Ripple Current is tested and specified over a 5 Hz to 20 MHz bandwidth. Input filtering is Cin=2 x

100 μF ceramic, Cbus=1000 μF electrolytic, Lbus=1 μH.

(3)

Note that Maximum Power Derating curves indicate an average current at nominal input voltage. At higher

temperatures and/or lower airflow, the DC/DC converter will tolerate brief full current outputs if the total

RMS current over time does not exceed the Derating curve.

(4a) Mean Time Before Failure is calculated using the Telcordia (Belcore) SR-332 Method 1, Case 3, ground fixed

conditions, Tpcboard=+25 ˚C, full output load, natural air convection.

(4b) Mean Time Before Failure is calculated using the MIL-HDBK-217N2 method, ground benign, +25ºC., full

output load, natural convection.

(5)

The On/Off Control Input should use either a switch or an open collector/open drain transistor referenced

to -Input Common. A logic gate may also be used by applying appropriate external voltages which do not

exceed +Vin.

(6)

Short circuit shutdown begins when the output voltage degrades approximately 2% from the selected

setting.
