Patent number: 10432093Abstract: A multiphase DC-DC converter includes a first phase circuit including a higher inductance inductor and a second phase circuit including a lower inductance inductor. An output of the inductors are tied together providing a Vout. A phase manager and current sharing (PMCS) block receives a feedback signal from a feedback network coupled between Vout and the PMCS block that receives current feedback from phase circuits. The PMCS block generates driver control signals at a first time when a load is requesting a lower load current for controlling the phase circuits to operate with a first current sharing ratio to provide the lower load current, and at a second time when the load is requesting a higher load current controls the phase circuits to operate at a second current sharing ratio that is different from the first current sharing ratio having a higher average second phase circuit current.Type: GrantFiled: October 23, 2017Date of Patent: October 1, 2019Assignee: Texas Instruments IncorporatedInventors: Kuang-Yao Cheng, Wenkai Wu, Yipeng Su
