PRODUCT OVERVIEW
The OKR-T/1.5-W12-C is a miniature SIP non-isolated Point-of-Load (PoL) DC/DC power converter
measuring only 0.41 x 0.40 x 0.24 inches (10.4 x 10.16 x 6.1 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), overcur-
rent and over temperature protections. These units are certified to UL/EN/ IEC 60950-1 safety standards
(2nd edition) and RoHS-6 hazardous substance compliance.

For Vout ≥ 3.3V, Vin should be ≥ (Vout ÷ 0.85) + 0.5V.
All specifications are at nominal line voltage, Vout=nominal (5V for W12 models) and full load, +25°C unless
otherwise noted.
Ripple and Noise (R/N) is 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 dif-
fers from the product photograph on page 1. Here is the layout of the label:

Figure 2. Label Artwork Layout
The label contains three rows of information:
First row – Murata Power Solutions logo
Second row – Model number product code (see table)
Third row – Manufacturing date code and revision level
Model Number
OKR-T/1.5-W12-C
Product Code

The manufacturing date code is four characters:
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)
