Disclosed examples include integrated circuits configurable according to sensed circuit conditions to provide configurable power converter topologies with externally connected circuitry to implement buck, boost, buck-boost, low dropout and/or hot-swap power converters. The ICs include one or more sets of series connected high and low side transistors connected with corresponding IC pads to allow connection to external circuitry to form a particular power converter configuration. The IC includes a control circuit and a configuration circuit to sense a circuit condition of the IC and to configure the control circuit to provide switching control signals to the transistors to implement one of a plurality of power converter topologies.
