LTC4440EMS8E-5 Datasheet PDF - Linear Technology

DESCRIPTION

●The LTC®4440-5 is a high frequency high side N-channel MOSFET gate driver that is designed to operate in applications with VINvoltages 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.
