Ultra-small power MOSFET gate drivers cut parasitic inductance problems
Each time a power MOSFET is being turned on or off in a SMPS, parasitic inductances produce ground-shifts that may cause false triggering of the gate-driver IC. Infineon Technologies AG adds a device to its cost-effective and compact-size EiceDRIVER 1EDN TDI (truly differential inputs) 1-channel gate-driver family to prevent such consequences. The new device (1EDN7550U) is […]
