An apparatus for generating an isolated power supply voltage and an isolated data signal includes a first pulse generation circuit configured to generate a first pulse signal and a second pulse generation circuit configured to generate a second pulse signal based on an input pulse width modulation (PWM) signal. A transformer circuit including a transformer is coupled to the first pulse generation circuit and to the second pulse generation circuit. The transformer is configured to generate an output pulse signal based on the first pulse signal and the second pulse signal. An isolated power supply circuit is coupled to the transformer circuit and is configured to generate an isolated power supply voltage based on the output pulse signal. A latch circuit is coupled to the transformer circuit and is configured to generate an isolated PWM signal based on the output pulse signal.
