Abstract: DC-DC converter PWM controllers and dual counter digital integrators are presented for integrating an error between a reference voltage signal and a feedback voltage signal, in which a comparator, dual counters, and a DAC are used to provide a compensated reference to a modulator loop comparator which generates a PWM switching signal for controlling a power converter output voltage, with the second counter being selectively incremented or decremented when the first counter output indicates a predetermined value after the first counter output transitions in one direction through a predetermined count range to enhance loop stability, and a startup mode control allows fast integrator operation during initialization, with the ability to freeze integrator operation during overcurrent conditions.

Abstract: A method for a DC to DC converter with a pseudo constant switching frequency is disclosed herein. For example, some embodiments provide a DC to DC converter having a switch connected to a switching node to control a voltage of the switching node, and a switching controller that is adapted to turn on and off the switch at a substantially constant frequency based at least in part on the voltage of the switching node. The switching controller includes a modulator connected to a control electrode of the switch and that is adapted to actuate and deactuate the switch, and a first timer that is connected to the switching node and to the modulator. The first timer uses the voltage of the switching node to determine an on-time for the switch.

Abstract: The disclosure provides an over-current protection circuit. A signal generating block in the over-current protection circuit generates one or more input voltages, a summed voltage and an average voltage in response to one or more differential voltages. A control block generates one or more control signals in response to the one or more input voltages and the average voltage. An analog control loop block generates an initiation signal in response to the summed voltage and an output voltage. A phase control logic block generates one or more PWM (pulse width modulated) signals in response to the initiation signal and the one or more control signals.
