Converter with dynamic loop compensation powers FPGAs, ASICs and processors

Murata has introduced the OKDL-T/60-W12, a 60A, 95% efficient addition to the OKD family of digitally controlled point of load (PoL) DC-DC converters. The power module is ideally suited for FPGA and processor applications. The module is specified to operate over a Vin range of 4.5V to 14VDC, and provides a user adjustable output in the range of 0.6VDC to 1.8VDC with an industry leading efficiency of 94.9%. The SMT/LGA module measures just 25.1mm x 14.1mm x 7mm, providing industry leading-power density for the most demanding applications. This highly efficient, PMBus compliant POL 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 device 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. See the data sheet for additional details. With all of the advanced features, high efficiency, and small SMT footprint, the device is an ideal solution for 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 device is certified by AMP 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 are certified to UL/IEC 60950-1 and sample quantities are available from stock with production lead times of eight weeks with a forecast.
