Abstract
A regulator circuit that employs coupled inductors with on-time modulation is disclosed. The regulator circuit includes a driver circuit coupled via first and second inductors to a power supply node of a load circuit, and may charge the power supply node via the first inductor for a first charging period, and charge the power supply node via the second inductor for a second charging period. A control circuit may determine durations of the first and second charging periods using respective pluralities of currents.
