A multiple-phase parallelable constant on time (COT) buck controller is disclosed, a first phase containing a first memory bit (116) and a second phase containing a second memory bit (116). The COT buck controller includes a first converter (112) comprising a first constant TON generator (118) configured to sense and deliver a first TON request when the first memory bit is in a logic one state, and a second converter (114) connected in parallel with the first converter, the second converter comprising a second constant TON generator (118) configured to sense and deliver a second TON request when the second memory bit is in the logic one state, only one of the first memory bit and the second memory bit being in the logic one state thus generating activity in a daisy chain ring where each ofthe first converter and the second converter senses and delivers a corresponding TON request in a sequential manner. 一种多相可并联恒定导通时间(COT)降压控制器，第一相位包含第一存储器位(116)，并且第二相位包含第二存储器位(116)。该COT降压控制器包括：第一转换器(112)，该第一转换器(112)包括第一恒定TON发生
