PRODUCT OVERVIEW
The OKL-T/3-W12 series are miniature
non-isolated Point-of-Load (PoL) DC/DC power
converters for embedded applications. Featuring
inspectable Land Grid Array (iLGA) format, the
OKL-T/3-W12 measures only 0.48 x 0.48 x 0.244
inches max. (12.2 x 12.2 x 6.2 mm max.).
The wide input range is 4.5 to 14 Volts DC.
The maximum output current is 3 Amps. Based
on fixed-frequency synchronous buck converter
switching topology, the high power conversion
efficient Point of Load (PoL) module features
programmable output voltage and On/Off control.
These converters also include under voltage lock
out (UVLO), output short circuit protection, and
over-current protections.
An optional sequence/tracking feature on
OKL2-T/3-W12 models allows power sequencing of
PoL’s. These units are certified to all standard UL/EN/
IEC 60950-1 safety certifications (2nd Edition) and
RoHS-6 hazardous substance compliance.

The output range is limited by Vin. See detailed specs.
All specifications are at nominal line voltage, Vout=nominal (5V for W12 models) and full load,
+25 deg.C. unless otherwise noted.
Output capacitors are 10 μF ceramic. Input cap is 22 μF. See detailed specifications.
I/O caps are necessary for our test equipment and may not be needed for your application.
Use adequate ground plane and copper thickness adjacent to the converter.
Ripple and Noise (R/N) and no-load input current are shown at Vout=1V. See specs for details.

Output Current (Note 7)
Current-limited. Devices can withstand a
sustained short circuit without damage.
The outputs are not intended to accept
appreciable reverse current.
Storage Temperature
-55 to +125 ˚C.
Lead Temperature
See soldering specifications
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 or recommended.
Specification Notes:
(1) Specifications are typical at +25 °C, Vin=nominal (+12V.), Vout=nominal (+5V), 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.
