Abstract
This paper presents the design and implementation of an integrated low-voltage power conversion controller capable of delivering MOSFET gate-drive signals to on-chip power transistors with precision timing. Analog dead-time-locked-loops (DTLL) are used to realize an accurate analog deadtime controller with fast error rejection in a fixed frequency zero-voltage-switching quasi-square-wave (ZVS-QSW) buck converter.
