LTC4440A-5
High Speed, High Voltage,
High Side Gate Driver
Features Description n n n The LTCВ®4440A-5 is a high frequency high side N-channel
MOSFET gate driver that is designed to operate in applications with VIN voltages up to 80V. The LTC4440A-5 can
also withstand and continue to function during 100V VIN
transients. The powerful driver capability reduces switching losses in MOSFETs with high gate capacitances. The
LTC4440A-5’s pull-up has a peak output current of 1.1A
and its pull-down has an output impedance of 1.85О©. n n n n n n Wide Operating VIN Range: Up to 80V
