Delta-based current steering for power converter peak/valley current control

A method, in a power converter system for converting an input voltage at an input of the power converter system into an output voltage at an output of the power converter system, wherein the power converter system comprises a switch network comprising a reactive circuit element and a plurality of switches and switch control circuitry configured to operate the plurality of switches in a plurality of periodic, sequential states to regulate the output voltage, the method comprising:

• comparing a current flowing through a sensed switch to a reference current with a comparator coupled to the sensed switch of the plurality of switches;
• and
• generating, with current-steering circuitry coupled to the comparator, the reference current and alternating the reference current between a first reference current and a second reference current whenever the switch control circuitry changes from one state of the plurality of periodic, sequential states to another state of the plurality of periodic, sequential states.

A method, for a circuit comprising a plurality of switches and switch control circuitry configured to operate the plurality of switches in a plurality of different switch states, the method comprising:

• comparing a current flowing through a sensed switch to a reference current with a comparator coupled to the sensed switch of the plurality of switches;
• and
• generating, with current-steering circuitry coupled to the comparator, the reference current and alternating the reference current between a first reference current and a second reference current whenever the switch control circuitry changes from one switch state to another switch state.
