PMBus PMIC (Industrial)
Infineon’s integrated power management IC is a five output Point of Load (POL) digital voltage regulator for FPGAs, ASICs, and other multi-rail power systems. The fully integrated PMIC solution replaces multiple regulators with a single device in a compact package. It is a perfect fit for current and future applications in high density ASIC and FPGA. Additional applications include CPU multi-rail systems, embedded computing systems, and communication and storage systems.
The IRPS5401 is designed for single rail operation ranging from 5 V to 12 V, where most PMICs are only 5 V. It has one 500 mA LDO output and four configurable switching regulator outputs (two at 2 A and two at 4 A). The outputs of the IRPS5401 can be used to provide the typical rails required for core, memory, and I/O voltages. All outputs are well within the power requirements of most FPGAs and ASICs ranging between 10 W to 50 W, including integrated voltage sequencing. Industry standard PMBus commands provide an easy-to-use interface for status and telemetry, and PMBus can be used to configure the output voltages in 5 mV steps.
