PoL converter has dynamic loop compensation for FPGAs, ASICs, and processors

An addition to the OKD family of digitally controlled PoL DC/DC converters has been announced by Murata. The OKDL-T/60-W12 is a 60A, 95 per cent efficient module.

It is suitable for FPGA and processor applications and is specified to operate over a Vin range of 4.5 to 14V DC. It provides a user-adjustable output in the range of 0.6 to 1.8V DC with an industry leading efficiency of 94.9 per cent, claims the company. The SMT/LGA module measures just 25.1 x 14.1 x 7.0mm.

The PMBus-compliant module is delivered with default firmware suitable for a range of applications and is 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 co-efficients by detecting output parameters.

According to the company, the OKDL-T/60-W12-xxx-C is suitable for critical applications in networking, computing, and telecomms 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). 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.
