Murata Power Solutions Inc. has introduced the first three models in its new Okami range of miniature non-isolated single output point-of-load (PoL) DC/DC converters.

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 Distributed-Power Open Standards Alliance (DOSA)-compliant parts or be used as a cost-competitive alternative to discrete designs in which reduced component count and shorter time-to-market are required.

Housed in an industry-standard 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 1,000?F. This makes the modules well-suited for powering the latest generation of FPGAs and DSPs that require tight output load regulation. The modules have an operating temperature range of -40C to +85C.

Fabricated on a 20.8mm x 12mm 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 percent (3.3Vout/5A) with no heat sink and no extra components. The design also results in very low heat and minimal electrical noise.

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. Delivery on both models is from six to eight weeks.
