Shenzhen Mingjiada Electronics Co., Ltd. [Supply, Recycle] LTC4449EDCB High Speed Synchronous N-Channel MOSFET Driver
Product Description
LTC4449EDCB is a high frequency gate driver that is designed to drive two N-Channel MOSFETs in a synchronous DC/DC converter. The powerful rail-to-rail driver capability reduces switching losses in MOSFETs with high gate capacitance. The LTC4449 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 LTC4449 activates a shutdown mode that turns off both external MOSFETs. The input logic signal is internally level-shifted to the bootstrapped supply, which functions at up to 42V above ground.
