LTC4449 Datasheet High Speed Synchronous N-Channel MOSFET

Manufacturer: Linear Technology (now Analog Devices)

General Description

The LTC®4449 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.
