Murata Power Solutions: New range of DC-DC converter products

Murata Power Solutions has added an expanded range of digitally controlled, PMBus™ compatible OKDL products to its Okami™ series of non-isolated point-of-load (PoL) DC-DC converters.

The OKDL-T/6-W12, OKDL-T/12-W12 and OKDL-T/18-W12 are designed to deliver 6, 12 and 18A respectively. The products also are capable of being monitored and configured via PMBus™ communications, accept input voltages from 4.5V to 14V, and feature 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 12.2 x 12.2 x 8.0 mm (0.48 x 0.48 x 0.315 in). The OKDL converters offer a typical efficiency figure of 91.6 percent at 12Vin and can operate in a temperature range of -30 to +95°C.

The wide operating temperature range makes the OKDL products ideal in applications such as networking, computing, servers, telecom, industrial and other distributed power uses, according to Murata. The products are designed to power low-voltage silicon devices such as CPUs, FPGAs, microcontrollers, logic circuits, memory and other analog/digital devices in mixed voltage systems.

Standard features include 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, synchronization to reduce EMI filtering, and an optimized dead time control.

"In the ever-changing and complex world of electronics, power systems are becoming more and more complicated. Power systems engineers face difficult challenges delivering low voltage, high current rails to FPGAs, ASICS and other critical electronic circuits," said Murata Product Manager Bill Smith in a press release. "The OKDL series of PMBus™ compliant PoLs delivers unmatched versatility for precise control and monitoring of the most sophisticated power systems."
