Abstract: A circuit may include a switching signal generator to generate a high-side switching signal and a low-side switching signal. A low-side switch may be connected to the output of the circuit and to the switching signal generator to receive the low-side switching signal. A plurality of high-side switches may be connected to corresponding inputs of the circuit. A matrix may be configured to selectively connect the high-side switching signal to two or more of the high-side switches.
