OKR-T/1.5-W12-C www.murata-ps.com Adjustable Output 1.5-Amp SIP-mount DC/DC Converters Typical unit FEATURES PRODUCT OVERVIEW The OKR-T/1.5-W12-C is a miniature SIP non-isolated Point-of-Load (PoL) DC/DC power converter 600 KHz operation 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 4.5-14 Vdc input voltage range DC. Based on 600 KHz synchronous buck topology, the high power conversion ef cient Point of Load (PoL) Programmable output voltage from 0.591-6.0 VDC module features programmable output voltage and On/Off control, under voltage lock out (UVLO), overcur- rent and over temperature protections. These units are certi ed to UL/EN/ IEC 60950-1 safety standards High power conversion ef ciency at 93% (2nd edition) and RoHS-6 hazardous substance compliance. Outstanding thermal derating performance Over temperature and over current protection On/Off control SIP, 0.41 x 0.40 x 0.24 inches (10.4 x 10.16 x 6.1 mm) Certi ed to UL/EN/IEC 60950-1 safety standards, 2nd edition RoHS-6 hazardous substance compliance Figure 1.

Product Label Because of the small size of these products, the product label contains a Model Number Product Code character-reduced code to indicate the model number and manufacturing date OKR-T/1.5-W12-C 54733 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: 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 XXXXXX Product code Mfg. O, N, D = Oct, Nov, Dec) date YMDX Rev. Revision level code Third character Day code (1 through 9 = 1 to 9, 10 = 0 and 11 through 31 = A through Z) Figure 2.
