Murata Adds New 12V Input SMT Modules To Family Of DOSA-Compliant PoL DC-DC Converters

May 21, 2009 by Jeff Shepard

Murata Power Solutions has added eight new 12V input models to its DOSA compliant Okami™ range of non-isolated point-of-load (PoL) dc-dc converters. The latest additions comprise four 10A and four 16A output current surface mount (SMT) modules that provide a 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 is a wide input voltage range of 8.3 to 14Vdc and a programmable, output voltage from 0.75 to 5.5Vdc, which simplify the inclusion of these modules into a wide range of equipment designs. Typical applications include any system using latest generation IC’s such as DSP, FPGA and ASIC.

The new OKAMI modules achieve power conversion efficiency of up to 94.5%, are said to have outstanding thermal derating performance and are able to support up to 1000µF ceramic output capacitance. The compact design incorporates over-temperature and short-circuit protection features with pre-bias immunity.

Operating temperature range is -40 to +85°C and the modules have dimensions of 33 (1.30) x 13.5 (0.53) x 8.4mm (0.33in.). The modules are designed to meet UL/EN/IEC 60950-1 safety approvals and FCC emissions certifications.
