Murata announced the first in a series of Point-of- Load (PoL) non-isolated DC-DC converters based on the Digital Control Architecture from Powervation. The DOSA compatible OKLF 25A PoL has been designed to address the industry's growing requirement for low voltages (1.25V and less), increased current and power densities, fast transient response times, and the need for a tightly regulated DC output voltage. The OKLF 25A PoL is ideal for powering the latest FPGAs and ASICs used in networking, telecommunications, and computing applications.

The first device in this new series is the OKLF-T/25-W12N-C. This PoL converter has been developed around a multi-processor System-on-Chip (SoC), digital power management IC from Powervation. Proprietary algorithms have been developed to optimize the performance under the most demanding applications, helping the power system engineer meet tight development (time-to-market) schedules. The converter delivers a maximum of 25 amps at 1.2 VDC out, when operating up to +70°C with a 200LFM airflow. Also, this model has been designed to operate over a wide input voltage range of 6.5 to 14 VDC. The OKLF 25A PoL power converter is an ideal option for power system engineers who require output stability under all operating conditions, industry leading efficiency, and a pin-programmable output voltage. Vout can be set in the range 0.69V to 3.63V using a single external resistor.

The OKLF series has an ultra-fast dynamic load response feature that automatically compensates for various external conditions including capacitive loading, current steps, temperature, input voltage, and Vout setting.

The use of Powervation's synchronous buck controller IC ensures industry-leading performance in the 25A class of PoL converters. The design incorporates Murata Power Solutions' proprietary thermal management techniques, custom magnetics, and several circuit protection features.

Production quantities priced to $11.25, with lead-times of 12-14 weeks.
