PoL dc/dc converters add 20, 30, 50 A devices

Three additions to the Okami OKR series of single output, non-isolated point of load (PoL) dc/dc converters feature space efficient single in-line package (SIP) format. The converters use the latest synchronous buck technology for 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 10-A range.

The 20-A model, OKR-T/20-W12-C, measures – 15.5 x 36.8 x 11.2 mm and accommodates a wide 6 to 13.8-Vdc input and a programmable output in the range 0.591 to 5 Vdc and efficiency up to 94%. The 30-A version OKR-T/30-W12-C model offers a 5.5 to 13.8-Vdc input and a 0.591 to 6-Vdc output with efficiency up to 95%. The 50-A OKR-T/50-W12-C converter has an input voltage range of 6.5 to 13.8 V, an output in the range 0.591 to 2.5 Vdc and measures 27.9 x 36.8 x 15.5 mm. The converter series includes over temperature, over current and under voltage lock out (UVLO). The series also have On/Off and remote sense capabilities.
