High-speed synchronous N-channel-MOSFET driver has powerful gate drive

摘要

Linear Technology's new high-speed LTC4449 synchronous MOSFET driver drives upper and lower power N-channel MOSFETs in a synchronous rectified-converter topology. This driver combines with a Linear Technology dc/dc controller and a power FET to form a complete high-efficiency synchronousrnregulator that can serve as a step-down or step-up dc/dc converter.
