This paper will discuss the effect of parasitics on the performance of high frequency eGaN POLs, methods to improve the circuit layout of a highly integrated 3D integrated POL module, and the thermal design of a high density module using advanced substrates with improved thermal conductivity. The final demonstration is a 900W/in3 12V 2MHz Alumina DBC eGaN converter which offers unmatched power density compared to state of the art industry products and research.
