Murata adds modules to Okami DC/DC converters

The parts complement the 12V input 3A, 5A, 10A and 16A modules recently introduced, and give designers a greater choice of alternatives to discrete design in providing high-efficiency point-of-load (PoL) power for their embedded applications.

The Distributed Power Open Standards Alliance (DOSA)-compatible modules are housed in industry-standard, surface-mount (SMT) packages and can act as a drop-in replacement for other DOSA-compliant parts.

Typical applications include powering CPUs, datacom/telecom systems, server and storage equipment, industrial systems and programmable logic and mixed-voltage designs.

The four parts all offer 5V input (2.4V DC - 5.5V DC) and comprise 3A and 5A output options, each with a choice of positive or negative on/off control.

Output voltage is programmable from 0.75V DC to 3.63V DC.

Okami DC/DC converters offer efficiency levels up to 94.5 per cent and are able to drive 1,000uF ceramic capacitive loads.

This makes them ideal for powering applications with tight output load regulation requirements, such as the latest FPGAs and DSPs.

The modules feature high thermal derating performance, and provide under-voltage lockout, output short-circuit protection, plus over-current and over-temperature protection.

Compact overall dimensions of 20.8mm x 11.9mm x 6.2mm allow the Okami 3A and 5A 5V input non-isolated DC/DC converters to be used in space-constrained applications.

Operating temperature range is -40C to +85C.

The modules are RoHS-compliant and are designed to meet UL/EN/IEC 60950-1 safety approvals and FCC emissions certifications.
