The LTC3869 incorporates a fixed dead time of 30 nanoseconds between the switching of the top gate (TG) and bottom gate (BG) MOSFET drivers. This dead time is a critical design feature that ensures the…
Here are some common reasons why residual voltage might be observed on the gate outputs of the LTC3869 when the controller is off:
1. Gate Capacitance Holding Charge MOSFET gates have parasitic capacitance…
