Infineon Technologies IRPS5401MXI03TRP

Overview

IRPS5401MXI03TRP from Infineon Technologies is a pre-programmed multi-output PMIC with integrated sequencer, designed specifically for Xilinx Zynq UltraScale+ ZU02–ZU09 SoCs. It delivers four synchronous buck regulators (A–D) and one ±0.5 A LDO, supports full PMBus 1.3 telemetry and fault management, and achieves ±0.5% output voltage accuracy across temperature and load.

For engineers reviewing the IRPS5401MXI03TRP datasheet, IRPS5401MXI03TRP pinout, IRPS5401MXI03TRP application for Zynq UltraScale+, or IRPS5401MXI03TRP equivalent, key selection criteria include pre-configured sequencing for ZU02–ZU09 power rails, integrated FETs eliminating external MOSFETs for outputs B–D, and PMBus-based margining of core (0.72 V), system (3.3 V), DDR (1.2 V), and auxiliary (1.8 V) supplies.

Technical Context

The IRPS5401MXI03TRP implements a fully integrated, pre-programmed power solution with four independent buck controllers (Ch A–D) and one linear regulator, all managed by an on-chip sequencer that executes fixed timing and dependency rules per Xilinx ZU02–ZU09 requirements. It uses internal high-side and low-side FETs for Channels B, C, and D, while Channel A supports external power stages up to 50 A via gate drivers.

PMBus 1.3 interface enables real-time telemetry (VOUT, IOUT, temperature), configurable fault responses (OCP, UVP, OVP), and precision margining (±1% step resolution) for all outputs. Sequencing is hard-coded in OTP memory and not user-modifiable - matching Zynq UltraScale+ boot-up voltage ramp order and hold times.

FAQ

Is IRPS5401MXI03TRP programmable after soldering?

No. The IRPS5401MXI03TRP contains factory-programmed OTP memory with fixed sequencing, voltage setpoints, and timing parameters for Zynq UltraScale+ ZU02–ZU09. It does not support runtime reprogramming or I²C-based configuration changes - unlike the blank IRPS5401MTRPBF variant.

What is the maximum supported current for Output A?

Output A delivers 2 A using internal FETs, but supports up to 50 A when paired with external power stages such as the TDA21240 (40 A) or TDA21242 (16 A). The MXI03TRP variant is pre-configured for 0.72 V core rail with gate drive outputs compatible only with those Infineon power stages.

Does this PMIC support pre-bias start-up?

Yes. All four buck channels feature monotonic soft-start with tracking capability and tolerate pre-biased output capacitors. The SS/TRK pins are internally tied to reference circuitry - no external components are required to ensure controlled ramp-up into powered-down downstream loads.

Can IRPS5401MXI03TRP be used with non-Xilinx SoCs?

It is technically possible but not recommended. Voltage setpoints, sequencing order, and timing delays are hardcoded for Zynq UltraScale+ ZU02–ZU09. Using it with other SoCs risks incorrect power-up order, violating VCCINT/VCCO ramp rate specs, or failing to assert PGOOD signals at required logic thresholds.
