Delivering conversion efficiency typically in the range of 93 - 95%, the OKL2-T/12 and the OKL2-T/20 have been added to Murata's Okami OKL range of non-isolated PoL DC/DC converters. Both devices incorporate the company's inspectable Land Grid Array (iLGA) package that allows ease of probing of all signal pads and visual inspection which is not possible when conventional LGA packages are used.

Measuring 20.32 x 11.43 x 8.55mm, the OKL2-T/12 delivers up to 12A output, with the 33.02 x 13.46 x 8.75mm packaged OKL2-T/20 providing 20A. Both devices are available in two varients which accomodate an input range around a nominal 5VDC (2.4 - 5.5VDC) or 12 VDC (4.5 - 14VDC). The 5V models provide a programmable output voltage in the range of 0.6 - 3.63VDC and the 12VDC models in the range 0.69 - 5.5VDC.

Featuring an operating temperature from - 40 to + 85°C, the series includes ULVO, output short circuit, overcurrent, and overtemperature. The devices can be synchronized using an external signal, with a remote on/off is also available with either negative or positive logic. Further to this, the output voltage is 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.

Due to achieving UL/EN/IEC 60950-1 safety approvals, the devices can be used in IT and computing equipment as well as space-constrained distributed power applications such as embedded computing, networking, and telecommunications equipment.
