Cherokee announces its next generation Polaris 2 half-brick DC/DC converter family. Delivering 120 A for the 1.2, 1.5 and 1.8 V versions, the Polaris 2 product family is able to achieve the performance of previous generation full bricks in a fraction of the size. The converter family also supports 2.5 V at 100 A, 3.3 V at 80 A and 5 V at 55 A. The Polaris 2 is an isolated, fixed-frequency design that uses synchronous rectification to achieve high efficiencies up to 92 percent and operates without derating at practical operating conditions of 300 linear feet per minute (LFM) airflow at 50° C. Measuring 2.42 inches× 2.4 inches× .45 inches, the Polaris 2 has a fast loop response to minimize peak deviations. The Polaris 2 family meets an input voltage transient requirement of 100 V for 100 milliseconds as well as insulation requirements for EN60950. The optional base-plate model enhances thermal performance in harsh environments.
