High Speed Synchronous N-Channel MOSFET Driver Delivers 5A for High Efficiency Buck or Boost DC/DC Converters

Linear Technology Corporation introduces the LTC4447, a high speed synchronous MOSFET driver designed to drive upper and lower power N-Channel MOSFETs in a synchronous rectified converter topology. This driver, combined with power MOSFETs and one of Linear Technology's DC/DC controllers, forms a complete high efficiency synchronous regulator that can be used as a step-down or step-up DC/DC converter.
