Chip-Level integration solves power design issues - A lot of problems with switch-mode dc-dc converters can be solved in silicon

摘要

Contemporary switch-mode dc-dc converters not only occupy significant area on the OEM circuit board, but they're also plagued by layout-dependent noise and stability issues. However, new breakthroughs in semiconductor processes and magnetic materials have enabled integration of the entire dc-dc converter, including ancillary components, into a single IC package. One result is enhanced control over the implementation, allowing converters to be made stable over a very wide range of I/O conditions with no layout-dependency issues.
