Abstract
A multiphase power supply includes several constant ON-time (COT) DC-DC converter integrated circuits (ICs). One of the COT DC-DC converter ICs generates a synchronization signal, which is received in parallel by the other COT DC-DC converter ICs. Two or more COT DC-DC converter ICs are turned ON at the same time in synchronization with the synchronization signal (e.g., an edge of a pulse of the synchronization signal) that is received in parallel and with another synchronization signal that is propagated from one COT DC-DC converter IC to another.
