Product details
Overview
IRPS5401MXI04TRPAUMA1 from Infineon is a pre-programmed, 5-output flexible power management IC (PMIC) integrating four switching regulators (4A/4A/2A/2A) and one 500mA source/sink LDO, operating from 5.5V–12V input with output voltage ranges of 0.25V–5.1V (switchers) and 0.5V–3.6V (LDO), designed for high-density multi-rail FPGA/CPU power systems.
For engineers reviewing the IRPS5401MXI04TRPAUMA1 datasheet, IRPS5401MXI04TRPAUMA1 pinout, IRPS5401MXI04TRPAUMA1 application, or IRPS5401MXI04TRPAUMA1 equivalent, key selection factors include its PMBus-enabled telemetry (voltage/current/temperature/faults), configurable current-sharing up to 50A via external IR MOSFET™ power stage, advanced sequencing control, and -40°C to +125°C junction temperature rating.
Technical Context
The IRPS5401MXI04TRPAUMA1 implements fixed-frequency emulated current-mode control across all four switchers-eliminating need for external compensation-and supports differential voltage sensing on Switcher A for ±0.5% output accuracy. Its integrated digital controller enables full PMBus v1.3 compliance with 74 commands, including real-time telemetry, programmable fault thresholds, and password-protected OTP configuration.
It features hardware-based power sequencing with independent enable/disable control per rail, sleep mode with <100µA quiescent current, and combined operation of Switchers C+D (8A) or Switcher A with external power stage (up to 50A). The LDO operates in source/sink mode with internal current limiting and thermal shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 5.5V to 12V single-rail operation-enables direct connection to standard intermediate bus without pre-regulation. |
| Switcher Output Currents | Configurable per Table 3: e.g., Config 4 = 0.85V/15A (A), 1.8V/2A (B), 1.2V/5A (C), 0.9V/0.5A (D)-supports high-current core rails with external PS option. |
| LDO Output | 500mA source/sink linear regulator with 0.5V–3.6V range-provides low-noise bias for analog/PLL circuits or I/O termination. |
| PMBus Interface | I²C/PMBus v1.3 with integrated level shifter and 74 supported commands-enables full telemetry, dynamic voltage scaling, and fault logging without external logic. |
| Operating Temperature | -40°C to +125°C TJ-qualified for industrial and embedded computing environments with sustained thermal stress. |
| Package | 7mm × 7mm, 56-pin QFN, 0.4mm pitch-optimized for high-density PCB layouts with thermal pad for efficient heat dissipation. |
Pinout & Package
IRPS5401MXI04TRPAUMA1 is housed in a thermally enhanced 7mm × 7mm, 56-pin QFN package with exposed thermal pad (pin 57 = GND). Pin assignment follows Infineon's standardized layout for PMBus-configurable PMICs, supporting simultaneous multi-rail monitoring and control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN_A–VIN_D | Switcher input supply pins | Independent input rails per switcher; decoupling required locally to minimize noise coupling between outputs. |
| BOOT_A–BOOT_D | High-side gate drive supply | Connect 0.1µF MLCC to corresponding PHASE pin; internal diode ties to VDRV-no external bootstrap diode needed. |
| PHASE_A–PHASE_D | Switch node outputs | Direct connection to output inductors; critical for EMI control and efficiency-requires short, low-inductance routing. |
| FB_A–FB_D, FB_L | Feedback inputs | Resistor-divider inputs for output voltage regulation; differential sensing on FB_A enables high-accuracy core rail control. |
| PG_A–PG_D, PG_L | Open-drain power-good signals | Individually monitor rail status; require external pull-up (e.g., 10kΩ to 5V) for system sequencing and fault isolation. |
| CLK / DATA / ALERT# | PMBus interface signals | Level-shifted I²C interface-operates at VDDIO voltage (1.8V typical); ALERT# asserts on masked faults for interrupt-driven diagnostics. |
Key Features
| Feature | Design Value |
|---|---|
| Emulated current-mode control | No external compensation required-reduces BOM count and design iteration time for stable loop response across load/line variations. |
| Differential voltage sensing (Switcher A) | ±0.5% output accuracy under load-critical for CPU/FPGA core voltage tolerance compliance (e.g., VR14/IMVP8). |
| Configurable current combining | Switchers C+D support parallel operation (8A); Switcher A supports external IR MOSFET™ stage (≥50A)-enables scalable power delivery architecture. |
| Integrated telemetry engine | Real-time reporting of voltage, current, die temperature, and faults over PMBus-eliminates need for external sense amplifiers or ADCs. |
| OTP memory + password protection | One-time programmable configuration storage with secure access-ensures consistent startup behavior and prevents accidental reconfiguration in fielded systems. |

|---|---|---|---|
| MP2965EK-LF-Z (Monolithic Power) | 4-switcher + 1-LDO, 600mA LDO, 4.5–18V input, no differential sensing, 64-pin QFN | Lacks PMBus telemetry depth (32 commands), no OTP, lower max current per switcher (3A/3A/2A/2A) | Preferred for cost-sensitive designs where telemetry and ultra-high accuracy are secondary to basic multi-rail delivery. |
| TPS546D24RQFT (TI) | Single 60A buck controller with external FETs, no integrated LDO, no PMBus-uses AVSBus | Requires external LDO, discrete current sensing, and separate sequencing IC-higher system complexity and board area | Selected when maximum flexibility in external power stage selection and >50A single-rail capability outweigh integration benefits. |

FAQ
What is the default configuration of IRPS5401MXI04TRPAUMA1?
This part is factory pre-programmed per Table 3 in the datasheet, with Config 4 (0.85V/15A on Switcher A, 1.8V/2A on B, 1.2V/5A on C, 0.9V/0.5A on D, LDO supplied externally at 2.5V). Configuration is stored in OTP memory and cannot be altered post-shipment.
Does IRPS5401MXI04TRPAUMA1 support external synchronization?
Yes-it accepts an external clock signal on the SYNC_IN pin (pin 31) to synchronize switching frequency across multiple devices, reducing beat frequencies and EMI in multi-PMIC systems. Supported input frequency range is 200kHz–1.2MHz, matching internal FSW settings.
How is current sensing implemented on Switcher A?
Current sensing uses integrated high-side MOSFET RDS(on) measurement with dedicated ISEN_A+ and ISEN_A− pins (pins 41–42), enabling accurate in-situ current telemetry without external sense resistors-critical for maintaining efficiency while supporting 50A+ external power stage configurations.
Can the LDO be used independently of the switchers?
Yes-the LDO (VO_LDO, pin 23) operates from VIN_LDO (pin 22), which accepts 1.2V–5.5V input independent of switcher inputs. It functions in source/sink mode with internal current limiting and can be enabled/disabled via EN_L (pin 27), allowing standalone use for analog bias or reference generation.
