Technical Examples

A sliding-mode switching power supply (24) having N phases (28) and a method of operating the power supply (24) are provided. N switches (30) are coupled to a bipolar power source (22), with each switch (30) effecting one phase (28). An inductance (32) is coupled to each switch (30), and a capacitance (36) is coupled to the inductances (32). A load (26) is coupled across the capacitance (36). A monitor circuit (38) is coupled to the inductances (32) and the capacitance (36) and configured to monitor currents (IL) through the inductances (32) and/or a voltage (VC) across the capacitance (36). A sliding-surface generator (78) is coupled to the monitor circuit (38) and generates a single sliding surface (?) for all phases (28). A constant-frequency control (104) forms a variable window (??) for the sliding surface (?). A switching circuit (138) switches the switches (30) at a switching frequency (fS) determined by the variable window (??). The constant-frequency control (104) adjusts the variable window (??) to maintain the switching frequency (fS) substantially constant.
