Original Abstract Submitted

Current balancing techniques. In an example, a circuit includes a synchronization terminal, an error amplifier, and a clock generator. The error amplifier is configured to generate a first control voltage signal based on a reference voltage and a power converter output voltage. The clock generator is configured to produce an outgoing clock signal having an outgoing clock frequency. The circuit further includes an encoder, a frequency detector, and a decoder. The encoder is coupled to the clock generator and synchronization terminal, and configured to encode the outgoing clock signal based on the first control voltage signal to provide, at synchronization terminal, an outgoing encoded clock signal. The frequency detector is coupled to synchronization terminal and configured to derive, from an incoming encoded clock signal, an incoming clock frequency. The decoder is coupled to synchronization terminal and configured to derive, from the incoming encoded clock signal, a second control voltage signal.
