Abstract: Several current sensing techniques are described that may be used to obtain an accurate current signal, which may help to achieve the best performance with a trans-inductor voltage regulator (TLVR) topology. The techniques may have the coupling effect from the secondary side included, so the current sensing signal is accurate for the regulation and other functions related to the current signal. The current sensing techniques may have more accurate gain and phase information in the middle frequency and high frequency ranges. The coupling effect from the secondary side may be well represented in the current sensing signal. The advantages of TLVR topology may be enhanced with accurate current information.
