Murata releases 12V Okami PoL DC/DC converters

A Murata Power Solutions product story

Edited by the Electronicstalk editorial team May 22, 2009

Murata Power Solutions has added eight 12V-input models to its DOSA-compliant Okami non-isolated point-of-load (PoL) DC/DC converter range.

The latest additions comprise of four 10A and four 16A output-current surface mount (SMT) modules that provide an ideal drop-in replacement for other DOSA-compliant parts in space-constrained designs that require high density, high-efficiency power solutions.

All OKY-T10 and -T16 modules are available with either positive or negative on/off logic control.

The OKY2-T10 and OKY2-T16 models offer the same choice but also feature a sequence/tracking function, wherein the output voltage will track an input signal to enable power sequencing.

Common to all models are a wide input voltage range of 8.3 to 14V DC and a programmable output-voltage from 0.75V to 5.5V DC, which aid the integration of these modules into a range of equipment designs.

Typical applications include any system using latest generation ICs such as DSP, FPGA and ASIC.

The new OKAMI modules achieve high-power conversion efficiency of up to 94.5 per cent, have outstanding thermal de-rating performance and can support up to 1000uF ceramic-output capacitance.

The compact design incorporates over-temperature and short-circuit protection features with pre-bias immunity.

Operating temperature range is -40C to +85C and the modules have dimensions of 33 x 13.5 x 8.4mm (1.30 x 0.53 x 0.33in).

The modules meet UL/EN/IEC 60950-1 safety approvals and FCC emissions certifications.
