OKL2-T/20-W12 Series www.murata-ps.com Programmable Output 20-Amp iLGA SMT PoL DC-DC Converter Series TTyypical unitpical uni FEATURES PRODUCT OVERVIEW The OKL2-T/20-W12 series are non-isolated The wide input range is 4.5 to 14Volts DC. iLGA inspectable Land Grid Array point-of-Load (PoL) DC-DC power converters for The maximum output current is 20Amps. Based 4.5-14Vdc input voltage range embedded applications. The tiny form factor is on xed-frequency synchronous buck converter Programmable output voltage from 0.69-5.5Vdc con gured on a Land Grid Array (LGA) assembly switching topology, the high power conversion measuring only 1.3 x 0.53 x0.34 inches (33.02 x ef cient Point of Load (PoL) module features pro- Drives 1000F ceramic capacitive loads 13.46 x 8.75 mm). Applications include powering grammable output voltage and On/Off control. High power conversion ef ciency at 94% CPUs, datacom/telecom systems, distributed bus These converters also include under voltage lock Outstanding thermal derating performance architectures (DBA), programmable logic and mixed out (UVLO), output short circuit protection, over- voltage systems. current and over temperature protections.

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 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.
