Murata Power Solutions Okami™ OKX DC/DC Converters

Murata Power Solutions Okami™ OKX Series are miniature SIP non-isolated Point-of-Load (PoL) DC/DC power converters for embedded applications. The OKX series modules are fully compatible with the Distributed-power Open Standards Alliance (DOSA) industry-standard specifications. Applications include powering CPUs, datacom/telecom systems, Distributed Bus Architecture (DBA), programmable logic, and mixed voltage systems. The Okami DC/DC power converters feature a wide input range of 8.3VDC to 14VDC and are offered in a 3A (T/3 models), 5A (T/5 models), 10A (T/10 models), or 16A (T/16 models) output current.

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. An optional Sequence/Track input allows controlled ramp-up and ramp-down outputs. The sense input provides load compensation. Murata Power Solutions OKX Series DC/DC converters also include Under Voltage Lock Out (UVLO), output short circuit protection, over-current, and over-temperature protection.
