Overview

The LM3477 is a current mode, high-side N channel FET controller. It is most commonly used in buck configurations. All the power conducting components of the circuit are external to the LM3477, so a large variety of inputs, outputs, and loads can be accommodated by the LM3477.

Features
  • 8-lead Mini-SO8 (MSOP-8) package
  • Internal push-pull driver with 1A peak current capability
  • Low current hysteric mode improves light load efficiency
  • Current limit and thermal shutdown
  • Frequency compensation optimized with a capacitor and resistor
  • Internal softstart
  • Current mode operation
  • Undervoltage lockout with hystersis
