PRODUCT OVERVIEW
The OKR-T/10 series are SIP non-isolated Point-of-Load (PoL) DC/DC power converters measuring
only 0.41 x 0.65 x 0.3 inches (10.4 x 16.5 x 7.62 mm). The wide input range is 4.5 to 14 Volts DC. Based
on 600 KHz synchronous buck topology, the high power conversion efficient Point of Load (PoL) module
features programmable output voltage and On/Off control, under voltage lock out (UVLO), overcurrent and
over temperature protections. These units meet all standard UL/EN/ IEC 60950-1 safety certifications and
RoHS-6 hazardous substance compliance.

For Vout ≥ 3.3V, Vin should be ≥ (Vout ÷ 0.85) + 0.5V.
Ripple and Noise is shown at Vout=1V. See specs for details.
All specifications are at nominal line voltage, Vout= 5V and full load, +25 deg.C. unless
otherwise noted. Output capacitors are 1 μF ceramic and| 10 μF electrolytic in parallel.
Input cap is 22 μF. See detailed specifications. I/O caps are necessary for our test equip-
ment and may not be needed for your application.
Vin must be 2V or higher than Vout for 3.3 to 5V outputs.

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 dif-
fers from the product photograph on page 1. Here is the layout of the label:
Model Number
OKR-T/10-W12-C

The label contains three rows of information:
First character – Last digit of manufacturing year, example 2009
Second character – Month code (1 through 9 = Jan-Sep;
O, N, D = Oct, Nov, Dec)
Third character – Day code (1 through 9 = 1 to 9, 10 = 0 and
11 through 31 = A through Z)
Fourth character – Manufacturing information
First row – Murata Power Solutions logo
Second row – Model number product code (see table)
