XYSemi XR6504B

SYNCHRONOUS BOOST CONVERTER With 7A Switch, Can Output 5V 3.4A with Li-Battery Input

Overview

TopologyBoost Converter
IC revision0.2

Description

XR6504/B is a high efficiency synchronous boost regulator that converts down to 2.5V input and up to 5.5V output voltage. It adopts NMOS for the main switch and PMOS for the synchronous switch. It can disconnect the output from input during the shutdown mode.. It integrates 7A power MOSFET and can output 5V 3.4A with Li-Battery input. XR6504B has Short circuit protection and Non-Backflow function, and XR6504 hasn't .

Features

  • 2.5V Minimum input voltage
  • Adjustable output voltage from 3V to 5. 5V
  • 8A peak current limit
  • Input under voltage lockout

  • Load disconnect during shutdown
  • Integrated soft-start
  • Output over voltage protection
  • 20mohm Power MOSFET
  • Thermal Shutdown
  • QFN3*3-15FC Package

Typical applications

  • •Handheld Devices
  • •All Single Cell Li or Dual Cell Battery Operated Products
  • •Power Bank
