PRODUCT OVERVIEW
The OKX-T/10 and -T/16 series are miniature
SIP non-isolated Point-of-Load (POL) DC/DC power
converters for embedded applications. The module
is fully compatible with Distributed-power Open
Standards Alliance (DOSA) industry-standard
specifications (www.dosapower.com). Applications
include powering CPU’s, datacom/telecom systems,
programmable logic and mixed voltage systems.
The wide input range is 8.3 to 14 Volts DC. Two
maximum output currents are offered, 10 Amps
(T/10 models) or 16 Amps (T/16 models). Based
on fixed-frequency synchronous buck converter
switching topology, the high power conversion
efficient Point of Load (POL) module features pro-
grammable output voltage and On/Off control. An
optional Sequence/Tracking input allows controlled
ramp-up and ramp-down outputs. The Sense input
provides load compensation. These converters also
include under voltage lock out (UVLO), output short
circuit protection, over-current and over tempera-
ture protections.
These units are designed to meet all standard
UL/EN/IEC 60950-1 safety and FCC EMI/RFI
emissions certifications and RoHS-6 hazardous
substance compliance.

Output Current (Note 7)
Current-limited. Devices can withstand a

The outputs are not intended to accept
appreciable reverse current.
Storage Temperature
-55 to +125 deg. 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 nor recommended.
Specification Notes:
(1) Specifications are typical at +25 deg.C, Vin=nominal (+12V. for D12 models), Vout=nominal (+5V for D12
models), full load, external caps and natural convection unless otherwise indicated. Extended tests at higher
power must supply substantial forced airflow.
All models are tested and specified with external 1 μF paralleled with 10 μF ceramic/tantalum 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 tantalum, 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, ISSUE 2,
ground fixed controlled conditions, Tambient=+25 deg.C, full output load, natural air convection.
(4b) Mean Time Before Failure is calculated using MIL-HDBK-217F, GB ground benign, Tambient=+25 deg.C, full
output load, natural air 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 not exceed
+Vin.
(6) Short circuit shutdown begins when the output voltage degrades approximately 2% from the selected
setting.
