Murata Power Solutions has released the Okami series of non-isolated point-of-load (PoL) DC-DC converters, which are capable of being monitored and configured via PMBus communications. The OKDL-T/6-W12, OKDL-T/12-W12, and OKDL-T/18-W12, deliver 6, 12, and 18A respectively. The products accept input voltages from 4.5V to 14V and have an adjustable output voltage range from 0.6V to 5V (1.8V max for 18A model).

Designed for a minimal footprint, the high-power-density LGA modules measure just 12.2mm x 12.2mm x 8.0mm (0.48in x 0.48in x 0.315in). The OKDL converters offer a figure of 91.6% at 12Vin, and are able to operate in a temperature range of -30 to +95C.

The operating temperature range of the OKDL products makes them work for applications such as networking, computing, servers, telecom, industrial, and other applications of distributed power. The products are designed to power low-voltage silicon devices such as CPUs, FPGAs, microcontrollers, logic circuits, memory, and other analogue/digital devices in mixed voltage systems.

With their digital control and PMBus compatibility, the converters offer easy user configuration and monitoring. All power management functions can be reconfigured for user-specific needs using the PMBus interface.

PoL converters

Included as standard features are short circuit, over current, over voltage, over temperature, and input under voltage protection, voltage margining and tracking, power good, remote sense, and remote on/off. The converters employ adaptive compensation of the PWM control loop, a phase spreading feature to reduce input capacitance, synchronisation to reduce EMI filtering, and an optimised dead time control. The OKDL converters are delivered with a default firmware configuration suitable for a wide range of input voltage, output voltage and load.

The OKDL products comply with the new "picoAMP" standard from the Architects of Modern Power (AMP) group of companies, which guarantees customers multiple sources of interoperable products.
