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.

Product Label
Because of the small size of these products, the product label contains a
character-reduced code to indicate the model number and manufacturing date
code. Not all items on the label are always used. Please note that the label
differs from the product photograph. Here is the layout of the label:
The label contains three rows of information:
