Product Details

The LTC4444 is a high frequency high voltage gate driver that drives two N-channel MOSFETs in a synchronous DC/DC converter with supply voltages up to 100V. This powerful driver reduces switching losses in MOSFETs with high gate capacitance. The LTC4444 is configured for two supply-independent inputs. The high side input logic signal is internally level‑shifted to the bootstrapped supply, which may function at up to 114V above ground.
