Point-of-load converters

23 September 2015 Power Electronics / Power Management

Murata has made 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 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 A, 30 A and 50 A devices to the existing 1,5 A, 3 A, 6 A and 10 A range.

The 20 A model, OKR-T/20-W12-C, measures just 15,5 x 36,8 x 11,2 mm and accommodates a wide 6 – 13,8 V input and a programmable output in the range 0,591 to 5 V and efficiency up to 94%. The 30 A, OKR-T/30-W12-C model offers a 5,5 to 13,8 V input and a 0,591 to 6 V output with efficiency up to 95%. The 50 A OKR-T/50-W12-C converter has an input voltage range of 6,5 – 13,8 V, an output in the range 0,591 to 2,5 V and measures 27,9 x 36,8 x 15,5 mm.

The OKR series includes a number of safety protection features such as over-temperature, over-current and under-voltage lockout (UVLO). They also feature 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.
