A converter system () includes a switch () adapted to be coupled to a switching terminal (). The switch () is configured to generate a switching signal having first and second states at the switching terminal (). Ripple generating circuitry () is adapted to be coupled to the switching terminal () and is configured to: generate a filtered signal based on the switching signal; and keep the filtered signal within a particular range. Loop control circuitry () is coupled to the ripple generating circuitry () and is configured to control the switch () based on the filtered signal.

DC-DC converters with loop control

A switch-mode power supply circuit includes a feedback terminal, a control circuit, a comparator, and a switch. The comparator includes a first input terminal coupled to a reference voltage source, and an output terminal coupled to an input terminal of the control circuit. The switch includes a first terminal coupled to the feedback terminal, a second terminal coupled to a second input terminal of the comparator, and a third terminal coupled to an output terminal of the control circuit.

Switch-mode power supply circuit

An example system includes an input voltage terminal; a power converter integrated circuit (IC) package fuselessly coupled to the input voltage terminal and having first and second pins, the power converter IC package configured to detect a short between the first and second pins; and a load circuit coupled to the power converter IC package.
