Note: Murata Power Solutions strongly recommends an external input fuse, F1.

See speciﬁ cations.

The OKL2-T/12-W12 series are miniature non-

isolated Point-of-Load (PoL) DC-DC power convert-

ers for embedded applications. The tiny form factor

is conﬁ gured on a Land Grid Array (LGA) assembly

measuring only 0.8 x 0.45 x 0.34 inches (20.32 x

11.43 x 8.55 mm). Applications include power-

ing CPUs, datacom/telecom systems, distributed

bus architectures (DBA), programmable logic, and

mixed voltage systems. The wide input range is 4.5

to 14 Volts DC.

The maximum output current is 12 Amps. Based

on ﬁ xed-frequency synchronous buck converter

switching topology, the high power conversion

efﬁ cient 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 and over

temperature protections.

OKL2-T/12-W12 Series Programmable Output 12-Amp iLGA SMT PoL DC-DC Converter Series TECHNICAL NOTES Output Voltage Adustment The output voltage may be adjusted over a limited range by connecting an external trim resistor (Rtrim) between the Trim pin and Ground. The Rtrim resistor must be a 1/10 Watt precision metal ﬁlm type,±0.5% accuracy or better with low temperature coefﬁcient, ±100 ppm/degC. or better. Mount the resistor close to the converter with very short leads or use a surface mount trim resistor.

OKL2-T/12-W12 Series Programmable Output 12-Amp iLGA SMT PoL DC-DC Converter Series Output Current Limiting Current limiting inception is deﬁned as the point at which full power falls below the rated tolerance. See the Performance/Functional Speciﬁcations. Note particularly that the output current may brieﬂy rise above its rated value in normal operation as long as the average output power is not exceeded. This enhances reliability and continued operation of your application.
