MURATA 15SEP264_ROBOkami OKR series of single output, non-isolated point of load (PoL) dc-dc converters are constructed in a space efficient single in-line package (SIP) format. Compact devices use the latest synchronous buck technology to deliver outstanding thermal performance, high power density and efficiencies as high as 95%. Models add 20, 30, and 50A devices to the existing 1.5, 3, 6, and 10A range. 20A model, OKR-T/20-W12-C, measures 15.5 x 36.8 x 11.2mm and accommodates a wide 6 thru 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 provides 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 27.9 x 36.8 x 15.5mm.
