Infineon – IRPS5401: Multi-Output PMIC with Integrated Sequencer


Infineon-Logo  NPI_LOGO
The IRPS5401 is a complete power management unit delivering up to 5 output voltages to processors, FPGAs 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.
