A module has been added to Murata Power Solutions' OKD family of digitally controlled Point of Load (PoL) DC/DC converters, the 60A, 95% efficient OKDL-T/60-W12. The OKDL-T/60 power module is suited for FPGA and processor applications. The module is specified to operate over a Vin range of 4.5-14VDC, and provides a user adjustable output in the range of 0.6-1.8VDC with an efficiency of 94.9%. 

The SMT/LGA module measures 25.1x14.1x7.0mm, providing power density for the most demanding applications.

This efficient, PMBus compliant POL module is delivered with a default firmware configuration suitable for a range of applications and is fully configurable to meet specific application requirements. The PMBus protocol provides full configuration and monitoring of the converter via a set of industry standard digital commands. The OKDL-T/60-W12 provides advanced power conversion management features such as Dynamic Loop Compensation (DLC). With DLC enabled the module will load loop compensation coefficients by detecting output parameters. With all of the advanced features, high efficiency, and small SMT footprint, the OKDL-T/60-W12-xxx-C is a useful solution for critical applications in networking, computing, and telecom systems. Other features include current sharing, voltage tracking, remote on/off control, synchronisation and phase spreading control that reduces input capacitance requirements and reduces efficiency losses in the application.

The OKDL-T/60-W12-xxx-C is certified by AMP (Architects of Modern Power) to be gigaAMP compliant and multi-sourced with true plug-and-play compatibility. The module protection features include output short circuit, over power, over voltage, over temperature, and input under voltage. The modules are certified to UL/IEC 60950-1.
