Murata Announces 5V Additions To OKAMI Family Of DOSA-Compliant PoL DC-DC Converters
Murata Power Solutions has added to its Okami™ non-isolated single point-of-load (PoL) dc-dc converters with an introduction of 3 and 5A modules with a 5V nominal input. The new parts complement the 12V input 3, 5, 10 and 16A modules recently introduced and are said to give designers an even greater choice of alternatives to discrete design in providing high efficiency Point-of-Load (PoL) power for their embedded applications.
The new 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 new parts all offer 5V input (2.4 – 5.5Vdc) and comprise 3 and 5A output options, each with a choice of either positive or negative on/off control. Output voltage is programmable from 0.75 to 3.63Vdc.
The new OKAMI dc-dc converters offer efficiency levels up to 94.5% and are able to drive 1000µF ceramic capacitive loads. This makes them suitable for powering applications with tight output load regulation requirements such as latest generation FPGAs and DSPs.
The company states that the modules have exceptional 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 (0.82in.) x 11.9mm (0.47in.) x 6.2mm (0.25in.) allow the OKAMI 3 and 5A 5V input non-isolated dc-dc converters to be used in space constrained applications. Operating temperature range is -40 to +85°C.
The modules are RoHS-compliant and are designed to meet UL/EN/IEC 60950-1 safety approvals and FCC emissions certifications.
