LTC4440-5 High Speed, High Voltage, High Side Gate Driver Description The LTC®4440-5 is a high frequency high side N-channel MOSFET gate driver that is designed to operate in applications with VIN voltages up to 60V. The LTC4440-5 can also withstand and continue to function during 80V VIN transients. The powerful driver capability reduces switching losses in MOSFETs with high gate capacitances. The LTC4440-5’s pull-up has a peak output current of 1.1A and its pull-down has an output impedance of 1.85Ω. The LTC4440-5 features supply independent...
