Abstract
A multiphase power supply includes several constant ON-time (COT) DC-DC converter integrated circuits (ICs), with each COT DC-DC converter IC providing an output voltage of a phase of the multiphase power supply. The COT DC-DC converter ICs are sequentially turned ON one after another in interleaved fashion. A COT DC-DC converter IC receives a control signal at a take pin and, in response, turns ON its output switch. The COT DC-DC converter IC generates another control signal at a pass pin. The next COT DC-DC converter IC turns ON its output switch in response to receiving the other control signal from the previous COT DC-DC converter IC.
