Each time a power MOSFET is turned on or off in a SMPS, parasitic inductances produce ground-shifts that may cause false triggering of the gate-driver IC. Infineon has added a device to its EiceDRIVER 1EDN TDI (truly differential inputs) 1-channel gate-driver family to prevent such consequences. The device (1EDN7550U) is housed in a 1.5 mm x ...
