www.DataSheet4U.com LTC4443/LTC4443-1 High Speed Synchronous N-Channel MOSFET Drivers FEATURES n n n n n n n n n n n n DESCRIPTION The LTC®4443 is a high frequency gate driver with integrated bootstrap Schottky diode designed to drive two N-channel MOSFETs in a synchronous buck DC/DC converter topology. The powerful driver capability reduces switching losses in MOSFETs with high gate capacitance. The LTC4443 features a separate supply for the input logic to match the signal swing of the controller IC. If the input signal is not being driven, the LTC4443 activates a shutdown mode that turns off both external MOSFETs. The input logic signal is internally level-shifted to the bootstrapped supply, which may function at up to 42V above ground.
