DC to DC Power Supplies (Converters)
DC/DC Converters come in DOSA-compliant SMT packages.
Press Release Summary:
With input range of 2.4-5.5 Vdc, OKAMI(TM) DC/DC Converters include models with 3 and 5 A output current. Non-isolated, point-of-load units each offer choice of positive or negative on/off control and programmable output voltage from 0.75-3.63 Vdc. Housed in 20.8 x 11.9 x 6.2 mm package, RoHS-compliant converters operate from -40 to +85°C with efficiency levels up to 96%, and can drive 1,000 µF ceramic capacitive loads, making them suited for powering FPGAs and DSPs.
Original Press Release:
Murata Power Solutions Announces 5V Additions to OKAMI(TM) Family of DOSA-Compliant PoL DC/DC Converters
o Able to drive 1000µF Ceramic capacitive loads
o DOSA compliant, industry standard SMT packages
o 2.4VDC - 5.5VDC input voltage range with choice of 3A and 5A output current models
o Programmable output voltage of 0.75VDC to 3.63VDC
o High power conversion efficiency up to 96%
The latest expansion of Murata Power Solutions' Okami(TM) non-isolated single point-of-load (PoL) DC/DC converters sees the introduction of 3A and 5A modules with a 5V nominal input. The new parts complement the 12V input 3A, 5A, 10A and 16A modules recently introduced and 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 (2.4VDC - 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 96% 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.
In high volume quantities, the 3Amp OKY-T/3 model is in the low $3 range and the 5Amp OKY-T/5 is below $4.00. Delivery on both models is from 6 to 8 weeks.
