SIP-format PoL converters add 20, 30 & 50A variants

July 16, 2015 // By Graham Prophet
Murata has grown its Okami OKR series of single output, non-isolated point of load (PoL) DC-DC converters. In a single in-line package (SIP) format, these are synchronous buck devices that deliver 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 5.5 x 36.8 x 11.2 mm, accepts a 6 – 13.8 VDC input and has a programmable output in the range 0.591 to 5VDC with efficiency up to 94%. The 30A, OKR-T/30-W12-C model accepts a 5.5 to 13.8 VDC input, has a 0.591 to 6 VDC output with efficiency up to 95%. The 50A OKR-T/50-W12-C has an input voltage range of 6.5V-13.8V, an output in the range 0.591 to 2.5 VDC and measures 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.
