XT1863 - DC-DC Boost Converter

Description

The XT1863 is a current mode step-up converter with a 4.5A, 0.08Ω internal switch to provide a highly efficient regulator with fast response.

The XT1863 operates at 1.5MHz allowing for easy filtering and low noise.

Features

  • Operating frequency: 1.5MHz.
  • Low Quiescent Current: 80μA.
  • PWM/PFM Mode.
  • 5V at 2A from Battery Li-ion.
  • True Shutdown from Load Path.
  • Package.
  • DFNWB3.
  • 3-8L XT1863 VOUT   0.6 1  R1 R2   ，VOUT- is the negative terminal of load path. This function is designed to shutdown the load path at any abnormal condition. If SHD is not used, please do not connect.
