    摘要: A method for an up-down converter which is based on a buck converter during the current down-conversion phase (Φ2, Φ3 and Φ5, Φ6, respectively) of the coil (L1) supplies an output (B) with a relatively high output voltage (UB), where UB>Uin. The down-conversion phase of the coil current (IL1) comprises at least two different down-conversion phases (Φ2, Φ3 and Φ5, Φ6, respectively). A method for an up-down converter, which converter is based on a boost converter, supplies during the current up-conversion phase (Φ7, and Φ10, respectively) of the coil (L2) an output (D) which has a relatively low output voltage (UD) with power, where UD>Uin. The up-conversion phase of the coil current (IL2) comprises at least two different current reduction phases (Φ7, Φ8 and Φ10, Φ11, respectively).

    摘要: An increasing number of phases in multiphase converters causes an increase in requirements with respect to the control IC. According to the present invention, instead of deriving a new PWM signal for every single phase of the DC-DC converter, the single phases are clustered into groups (22, 24, 26). Within each group, the converters are operated on the basis of one PWM signal (PW M1, PW M2 . . . PW MN). Advantageously, this may allow to reduce the requirements with respect to the control IC and thus may allow the application of cheaper and smaller control ICs.
