New 20A, 30A and 50A models expand compact SIP POL converter series

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, the 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 20A, 30A, and 50A devices to the existing 1.5A, 3A, 6A, and 10A range. The 20A model, OKR-T/20-W12-C, measures just 15.5mm x 36.8mm x 11.2mm 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 2.5VDC and measures just 27.9mm x 36.8mm x 15.5mm. 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 include powering CPUs, ASICs, FPGAs, DDR3 and DDR4, as well as use in other distributed bus architectures, says the company.
