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 (2.4VDC – 5.5VDC) and comprise 3A and 5A output options, each with a choice of either positive or negative on/off control. Output voltage is programmable from 0.75VDC 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 ideal for powering applications with tight output load regulation requirements such as latest generation FPGAs and DSPs.
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 3A and 5A 5V input non-isolated DC/DC Converters to be used in space constrained applications. Operating temperature range is -40ºC to +85ºC.
The modules are RoHS-compliant and are designed to meet UL/EN/IEC 60950-1 safety approvals and FCC emissions certifications.
