Abstract
A buck converter using a low-voltage GaN nMOS
power transistor with 5–10 × superior switching figure-of-merit
over Si laterally-diffused MOS (LDMOS) and stacked CMOS
at 5 V has been employed to build a high-frequency (3–20 MHz),
high-density (9 A/mm
2 ) buck converter for high-performance-
compute applications. The GaN-based converter is co-packaged
with a CMOS Companion Die on a 4 mm × 4 mm package
and employs on-die gate clamps to minimize the impact of
package parasitics for high efficiency. Fo
