Description

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.

Integrated, accurate current, voltage and temperature sensing allows telemetry and fault reporting through the

I2C/PMBus.

The IRPS5401 switching regulators utilize fixed frequency emulated current mode control, and thus no external

compensation is required.

The IRPS5401 is highly flexible. Switchers A and B deliver 2A each. Switchers C and D, deliver 4A each and can

also be combined to deliver 8A. Further, Switcher A can be configured to use an external IR MOSFET™ Power

Stage to deliver up to 50A or more.
