Murata has announced three additions to its Okami OKR series of single output, non-isolated point of load (PoL) dc-dc converters. Constructed in a space efficient single in-line package (SIP) format, these compact devices use the latest synchronous buck technology to deliver outstanding thermal performance, high power density, and efficiencies as high as 95%.
The new models add 20, 30, and 50A devices to the existing 1.5, 3, 6, and 10A range. The 20A model, OKR-T/20-W12-C, measures just 15.5 x 36.8 x 11.2 mm and accommodates a wide 6 - 13.8VDC input and a programmable output in the range 0.591 to 5VDC and efficiency up to 94%. The 30A, OKR-T/30-W12-C model offers a 5.5 to 13.8VDC input and a 0.591 to 6VDC output with efficiency up to 95%. The 50A OKR-T/50-W12-C converter has an input voltage range of 6.5V-13.8V, an output in the range 0.591 to 2.5 VDC and measures just 27.9 x 36.8 x 15.5 mm.
The OKR series include a number of safety protection features such as over temperature, over current and under voltage lock out (UVLO). The series also have On/Off and remote sense capabilities.Typical applications for the OKR series include powering CPUs, ASICs, FPGAs, DDR3 and DDR4, as well as use in other distributed bus architectures.
