LT8349 - 2-Phase Low IQ Synchronous Boost Converter

General Description

The LT8349 is a 2-phase single output synchronous boost converter that drives two internal N-Channel power MOSFET stages out-of-phase.

Multiphase operation reduces input and output capacitor requirements and allows the use of smaller inductors than the single-phase equivalent.

Key Features

  • Input Voltage Range: 2.5V to 5.5V.
  • Output Voltage Programmable Up to 8V.
  • 2-Phase Operation Reduces Required Input and Output Capacitance and Power Supply Induced Noise.
  • Synchronous Operation for High Efficiency and Reduced Heat Dissipation.
  • Stage SheddingTM and Optional Burst Mode® Operation for High Efficiency at Light Load.
  • Low VIN Pin Quiescent Current:.
  • 0.5µA in Shutdown.
  • 15µA in Burst Mode Operation.
  • Integrated 8V/6A Synchronous Power Switches.
