IRPS5401M

Overview

The IRPS5401 is a complete power management unit delivering up to 5 output voltages to processors, FPGA’s and other multi-rail power systems. Four high efficiency configurable switching regulators and a source/sink linear regulator provide the typical rails required such as core voltage, memory voltage and I/O voltages.

Summary of Features

  • Full power system including 5 integrated outputs
    • 4 A, 4 A, 2 A and 2 A switching regulators 
    • 500 mA source/sink linear regulator
  • Single rail operation 5 V to 12 V
  • Output range from 0.25 V to 5.1 V for outputs A-D and 0.5 V to 3.6 V for LDO
  • Allows combining outputs and/or the use of an external power stage to increase output current to as high as 50 A
  • Emulated current mode control without external compensation
  • Differential voltage sensing on switcher A for higher accuracy
  • I2C / PMBus with integrated level shifter
  • Advanced sequencing control
  • Extensive PMBus command set of 74 commands
  • Integrated current sensing and full telemetry including voltage, current, temperature and faults
  • Rated for -40°C to +125°C TJ operation
  • Pb-free, RoHS6, 7x7 mm, 56-pin, 0.4 mm pitch QFN
