Embarking on a New Frontier of Power Density with GaN (Download)

We’ll kick off this article with a power component recently introduced by Efficient Power Conversion (EPC): the EPC2361 enhancement-mode GaN FET at 100 V, 1 mΩ, housed in a 3- × 5-mm QFN package. This component offers a higher power density for DC-DC conversion, motor drives, fast charging, and solar maximum power point tracking (MPPT). Claimed as the lowest on-resistance GaN FET on the market, it offers twice the power density when compared to EPC’s earlier generation products.

Driven by such a FET or similar types of components, let’s look at high-power-density applications that are pushing the limits of power design.
