Press Release Summary:
Models OKY-T/3-D12P-C, OKY-T/3-D12N-C, and OKY-T/5-D12N-C miniature non-isolated, single-output, point-of-load DC/DC converters provide input voltage range of 8.3-14 Vdc and selectable output from 0.75-5.5 Vdc. Operating in temperatures from -40 to +85°C, they are used with capacitance loads of up to 1,000 µF and offer narrow line/load regulation and efficiency of up to 93%. Units are housed in DOSA-compliant 0.82 x 0.47 in. module with fixed-frequency buck switching topology.
Original Press Release:
OKY-T/3 & OKY-T/5 Series: World's Number One Board-Mounted Power Company Introduces First Three Models in Okami(TM) DOSA-Compliant Point-of-Load DC/DC Converter Range
o Okami modules provide drop-in replacement for DOSA PoL converters and competitive alternative to discrete designs
o Choice of 3A and 5A output current
o Wide input voltage range and user selectable output voltage
o Fixed-frequency buck switching topology gives efficiency to 93% , low heat and low noise
o High load capacitance to 1000µF
o Virtually no derating across rated temperature range
Murata Power Solutions has introduced the first three models in its new Okami(TM) range of miniature non-isolated single output point-of-load (PoL) DC/DC converters. The new modules represent the latest innovation from Murata Power Solutions, further strengthening its position as the world's number one supplier in the board mounted power sector.
The OKY-T/3-D12P-C, OKY-T/3-D12N-C and OKY-T/5-D12N-C provide designers of equipment requiring high efficiency PoL power with compact and reliable solutions that deliver respective output currents of 3A and 5A. The modules can act as a drop-in replacement for other DOSA-compliant parts or be used as a cost-competitive alternative to discrete designs where reduced component count and shorter time-to-market are required.
Housed in an industry-standard Distributed-Power Open Standards Alliance (DOSA) surface-mount package, the Okami OKY-T/3-D12P-C, OKY-T/3-D12N-C and OKY-T/5-D12N-C have a wide input voltage range of 8.3VDC to 14VDC (nominal 12VDC) and can be used with high capacitance loads of up to 1000µF. This makes the modules ideal for powering the latest generation of FPGAs and DSPs that require tight output load regulation. The modules have an operating temperature range of -40°C to +85°C.
Fabricated on a 20.8mm (0.82in.) x 12mm (0.47in.) surface mount module and using fixed-frequency buck switching topology, the OKY-T/3 and OKY-T/5 offer narrow line/load regulation and achieve high efficiency levels of up to 93% (3.3Vout/5A) with no heatsink and no extra components. The design also results in very low heat and minimal electrical noise.
All of the new models provide a user selectable output (via a precision resistor) of 0.75VDC to 5.5VDC and incorporate a remote on/off control. Inputs are protected from undervoltage whilst outputs have short circuit protection plus overcurrent and excess temperature shutdown.
The modules are RoHS-compliant, have an MSL (moisture sensitivity level) rating of 2, 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.
