Topology-independent switching regulator circuit, switch mode driver, and luminaire

An integrated circuit, IC (1), for switching regulation of switch mode drivers (2) of various driver topologies, the IC (1) comprising:

• a state machine (11) including a finite plurality of states (Sx);
• a quantity of the plurality of states (Sx) being adaptable to a designated driver topology (21) of the various driver topologies;
• a behavior of the plurality of states (Sx) being adaptable to the designated driver topology (21) via respective state registers (111) in terms of
• at least one action (1111) being executed in the respective state, and
• at least one transition from the respective state to a subsequent state of the plurality of states (Sx) according to an associated stimulus;
• and
• a number of peripheral mappings, being adaptable to the designated driver topology (21) via respective peripheral registers (121) in terms of a mapping of at least one sense pin (SENSE x) of the designated driver topology (21) and at least one analog resource of the IC (1), wherein the at least one analog resource comprises one or more of a comparator (comp_x, comp_zx), a clamper (neg_clamp, pos_clamp), an analog-to-digital converter (ADC), and a digital input.
