Murata Manufacturing Co. Ltd. today announced two additions to the Okami OKL range of non-isolated point-of-load (PoL) dc-dc converters manufactured by Murata Power Solutions. The OKL2-T/12 and the OKL2-T/20 converters feature Murata’s innovative inspectable Land Grid Array (iLGA) package that allows ease of probing of all signal pads and visual inspection that is not possible when conventional LGA packages are used. Both models are highly efficient with conversion efficiency typically in the range of 93 – 95%. The OKL2 series suit space-constrained distributed power applications such as embedded computing, networking, and telecommunications equipment.
The OKL2-T/12, measuring just 20.32 x 11.43 x 8.55 mm, delivers up to 12A of current, and the OKL2-T/20 provides 20A from a 33.02 x 13.46 x 8.75 mm package. Both models have two variants that accommodate a wide input range around a nominal 5 Vdc (2.4 – 5.5 Vdc) or 12 Vdc (4.5 – 14 Vdc). The 5-Vdc models provide a programmable output voltage in the range of 0.6 – 3.63 Vdc and the 12-Vdc models in the range 0.69 – 5.5 Vdc.
Safety and protection features of the OKL2 series include under voltage lockout (ULVO), output short circuit, overcurrent, and over-temperature. Remote on/off is available with either negative or positive logic. The converters are also capable of being synchronized using an external signal. The output voltage is also capable of being sequenced, or tracked, to an external input voltage. Multiple converters can track their output voltages in this way up to the set Vout voltage.
The modules have UL/EN/IEC 60950-1 safety approvals for use in IT and computing equipment. The OKL2 series is suitable for use in a wide range of environments with an operating temperature from -40 to +85 degrees C. Depending on the specific model and quantity, OEM pricing can range from as low as $6.50 to $7.50, with lead-times from stock to 10 weeks.
