Abstract: In at least one example, an apparatus includes a current sense circuit, an imbalance detector, and a current balancer. The current sense circuit including a first phase input, a second phase input, a first sense output, and a second sense output. The imbalance detector having a detector output, a first detector input, and second detector input. The first detector input is coupled to the first sense output and the second detector input is coupled to the second sense output. The current balancer having a balancer input and a balancer output. The balancer input is coupled to the detector output.

Abstract: A DC-DC converter includes a ramp generator, a threshold voltage circuit, and a control circuit. The ramp generator is configured to generate a voltage ramp. The threshold voltage circuit is configured to generate a threshold voltage. The control circuit is coupled to the ramp generator and the threshold voltage circuit. The control circuit includes a digital pulse width modulator (DPWM) circuit and a loop compensation circuit coupled to the DPWM circuit. The DPWM circuit is configured to generate a power stage switch control signal responsive to a loop compensation value. The loop compensation circuit is coupled to the DPWM circuit. The loop compensation circuit is configured to calculate the loop compensation value responsive to the voltage ramp exceeding the threshold voltage.
