Abstract
An isolation device having first and second semiconductor is disclosed. The first semiconductor die may be adapted to transmit a first signal to the second semiconductor die that is electrically isolated. The first semiconductor die may have a transmitter coupled to a modulator that modulates the first signal. The second semiconductor die may have a receiver having a counter and a control circuit. The control circuit may be adapted to determine an indication of the first signal by using the counter. In addition, an isolation system and a DC-DC feedback regulation control system having such control circuit are disclosed. Likewise, a method for conveying a first signal across an isolation barrier is disclosed. The method may comprise counting a received signal based on internal clock and determining an indication of the first signal from the counter's count value.
