60A PMBus PoL converter features dynamic loop compensation

December 01, 2016 // By Graham Prophet
Intended for tasks such as point-of-load supply to FPGAs, ASICs, and processors, Murata’s OKDL-T/60-W12 is a 60A, 95% efficient addition to the company’s OKD family of digitally controlled point of load (PoL) DC-DC converters.

The OKDL-T/60 power module is suited for FPGA and processor applications. The module is specified to operate over a Vin range of 4.5V to 14 VDC, and provides a user adjustable output in the range of 0.6 VDC to 1.8 VDC with efficiency of 94.9%. The SMT/LGA module measures 25.1 x 14.1 x 7.0 mm, providing leading-power density.


The module is delivered with a default firmware configuration suitable for a wide 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 the ideal loop compensation coefficients by detecting output parameters. Other features include Current Sharing, Voltage Tracking, remote On/Off control, synchronization, 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 group: Murata, CUI and Ericsson) to be gigaAMP compliant and fully multi-sourced with true plug-and-play compatibility. The module’s 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.
