OKL2-T/20-W5 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-W5 series are non-isolated The wide input range is 2.4 to 5.5Volts DC. iLGA inspectable Land Grid Array point-of-Load(PoL) DC-DC power Converters for The maximum output current is 20Amps. Based 2.4-5.5Vdc input voltage range embedded applications. The tiny form factor is on xed-frequency synchronous buck converter Programmable output voltage from 0.6-3.63Vdc 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 93% 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.
