DC-DC converters for power electronics uses in embedded computing introduced by Murata
MANSFIELD, Mass. – Murata Power Solutions in Mansfield, Mass., is introducing the 90A/162W OKDx-T/90 series digital PoL DC-DC converters for space-constrained embedded computing applications where power electronics performance is critical.
The module is specified to operate over a voltage input range of 7.5 to 14 volts and provides a user-adjustable voltage output range of 0.6 to 1.8 volts DC with efficiency of 94 percent.
The OKDx-T/90 is available in three different package configurations: SIP measuring 2 by 0.37 by 0.75 inches; horizontal mounting through-hole; and SMT versions measuring 2 by 0.75 by 0.39 inches.
The OKDx-T/90 is for field-programmable gate array (FPGA) and processor applications. Critical performance parameters are accessible through the PMBus via the Murata Power Designer GUI software.
The OKDx-T/90-W12 series converters come with a default firmware configuration suitable for a wide operating range in input voltage, output voltage, and loading conditions.
The OKDx-T/90 operates over a voltage input range from 7.5 to 14 volts; voltage output can be adjusted from 0.6 to 1.8 volts, with a typical efficiency of 94 percent with 12 voltage input, at 1.8 volts out and 50 percent load.
The synchronization feature eliminates beat frequency reflection, resulting in less EMI filtering, and digital current sharing ensures near 100 percent current sharing accuracy with as many as four modules operating in parallel.
The converters provide dynamic loop compensation, where the feedback loop parameters are automatically calculated and configured depending on operating conditions.
Additional standard features include output short circuit, over current, over voltage, over temperature, and input under voltage protection. Voltage margining, tracking, power good, remote sense, and remote on/off are also features commonly used in advanced power architectures.
