... Oscillations on the gates of the high-side MOSFET in discontinuous mode are a natural occurrence caused by the LC network formed by the inductor and stray capacitance at the LX_ pins. The negative side of the BST_ capacitor is connected to the LX_ node, so ringing at the inductor is translated through to the gate drive. Si786 Vishay Siliconix www.vishay.com 9 ...
