Digital PMBus compliant PoL converter to power FPGAs, ASICs and processors

Murata has introduced the OKDL-T/60-W12, a 60 Amp, 95 % efficient addition to its OKD family of digitally controlled point of load (PoL) DC-DC converters.

The OKDL-T/60 power module is intended to power 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 an efficiency of 94.9%. The SMT/LGA module measures just 25.1 x 14.1 x 7.0 mm.

Highly efficient, this PMBus compliant POL module comes with a default firmware configuration that is 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). DLC enabled the module is able to load the most effective loop compensation coefficients by detecting output parameters.

Combining advanced features with high efficiency, and small SMT footprint, the converter is intended for arrange of critical applications in networking, computing, and telecom systems.

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) to be gigaAMPTM 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 have been certified to UL/IEC 60950-1.
