Murata Power Solutions Okami™ OKL Series

The Murata Power Solutions OKL-T/3 series are miniature non-isolated Point-of-Load (POL) DC/DC power converters for embedded applications. The tiny form factor is configured on a LandGrid Array (LGA) assembly measuring only 0.488 x 0.488 x 0.22 inches(12.4 x 12.4 x 5.6 mm). Applications include powering CPU's,datacom/telecom systems, distributed bus architectures (DBA),programmable logic and mixed voltage systems.

The wide input range is 2.4 to 14 Volts DC. The maximum output current is 3 or 6 Amps. Based on fixed-frequency synchronous buck converter switching topology, the high power conversion efficient Point of Load (POL) module features programmable output voltage and On/Off control. These converters also include under voltage lock out (UVLO), output short circuit protection, over current and over temperature protections.

An optional sequence/track input on OKL2 models allows the output to follow an external voltage input forcontrolled (ramp) startup and shutdown. These units are designed tomeet all standard UL/ EN/IEC 60950-1 safety and FCC EMI/RFI emissionscertifications and RoHS-6 hazardous substance compliance.
