Product details
Overview
IR38060MGM18TRP from Infineon Technologies is a digitally configurable, synchronous buck DC-DC converter with integrated high- and low-side MOSFETs, delivering up to 6 A output current at 1.8 V nominal output voltage, 607 kHz fixed switching frequency, and PMBus/I²C interface for real-time telemetry and configuration in server point-of-load applications.
For engineers reviewing the IR38060MGM18TRP datasheet, IR38060MGM18TRP pinout, IR38060MGM18TRP application, or IR38060MGM18TRP equivalent, key selection criteria include its 0.5% reference accuracy, true differential remote sensing, thermally compensated overcurrent protection, and pre-configured 1.8 V/607 kHz operation-critical for stable core voltage regulation in high-density computing systems.
Technical Context
The IR38060 implements a voltage-mode PWM controller with internal LDO biasing (VCC = 4.5–5.5 V), enabling single-supply operation from 5.5–16 V PVIN. Its digital control loop supports 66 PMBus commands for configuration storage, fault logging, and telemetry-including real-time IMON (output current) and TMON (junction temperature) analog outputs in non-digital mode.
It integrates dual MOSFETs (RDS(on) = 14–27 mΩ top, 6–12 mΩ bottom), bootstrap diode, and dedicated PGOOD with output voltage sensing active even during disable. The device supports sequencing via TRACK_EN and VP pins, and operates across –40 °C to +125 °C junction temperature with 30 °C/W θJA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.8 V ±1.0% (–40 °C to +125 °C), pre-programmed in OTP memory-eliminates external resistor divider and ensures repeatable rail accuracy. |
| Max Output Current | 6 A continuous-supports high-current CPU/GPU core rails without external current-sense amplifiers or thermal derating below 125 °C. |
| Switching Frequency | 607 kHz fixed (pre-configured)-optimized for low EMI and high efficiency with standard 0.47–1 µH inductors and 22 µF ceramic output capacitors. |
| Reference Accuracy | ±0.5% at 25 °C, ±1.0% over full temp range-enables tight regulation margins required by DDR4/DDR5 memory and ASIC core supplies. |
| PMBus Interface | 400 kHz Fast Mode I²C-compatible-allows runtime margining, fault reporting (OCP, OVP, OT), and telemetry (IOUT, VOUT, TJ) without host firmware changes. |
| Remote Sensing | True differential RS+ / RS– inputs with RSO output-compensates for PCB trace IR drop up to 20 mV, maintaining ±0.5% load regulation at full 6 A. |
| Thermal Protection | Thermally compensated current limit + dedicated TMON analog output-enables predictive thermal throttling and eliminates need for external temperature sensors. |
Pinout & Package
IR38060MGM18TRP is housed in a thermally enhanced 5 mm × 6 mm PQFN package with exposed thermal pad (PGND-connected), supporting ≤30 °C/W junction-to-ambient dissipation under typical 2-layer PCB layout with 2 oz copper and 4 thermal vias.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PVIN (1) | Main power input for high-side switch | Accepts 5.5–16 V bus; requires local 4×22 µF + 0.1 µF ceramic bypassing to PGND to suppress SW node ringing. |
| BOOT (2) | High-side gate driver supply | Connects via 0.1 µF capacitor to SW; series 0 Ω (or 1 Ω if PVIN > 12 V) enables robust gate drive under transient load steps. |
| TRACK_EN (3) | Tracking enable control | Pulled to P1V8 via 100 kΩ to disable tracking; asserted low enables synchronized startup with master rail in multi-rail systems. |
| Vsns (5) | OVP and PGOOD sense input | Dedicated high-impedance input monitors output directly-ensures PGOOD assertion remains valid even when EN is low. |
| RS+ / RS– (10/9) | Differential remote sense inputs | Connect RS+ to load VOUT, RS– to load GND-enables <±0.5% load regulation independent of PCB resistance. |
| SCL/OCSet (19) | PMBus clock / analog OCP threshold | In analog mode, 4.7 kΩ pull-down sets overcurrent trip; in digital mode, functions as SMBus clock with 1–5 kΩ pull-up to 3.3–5 V. |
| SDA/IMON (18) | PMBus data / analog current monitor | Provides 0–2 V analog voltage proportional to IOUT (1 V/A scale); also serves as bidirectional SMBus data line with open-drain logic. |
| SALERT/TMON (17) | Alert output / analog temperature monitor | Open-drain SMBALERT# signal; in analog mode, outputs 0–2 V linear voltage proportional to TJ (10 mV/°C). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Power Stage | Monolithic 6 A buck stage with matched RDS(on) MOSFETs (14/6 mΩ typ) and bootstrap diode-reduces BOM count by 7 components vs discrete controllers. |
| Dual-Mode Operation | Runs fully configured via PMBus *or* as analog regulator with zero programming-supports legacy designs while enabling future digital upgrades. |
| Pre-Bias Start-Up | Soft-start initiates only when output is below target-prevents reverse current into pre-biased loads like FPGA I/O banks or memory modules. |
| Configurable Fault Response | Programmable OCP behavior (latch-off, hiccup, or current limit) via PMBus command-matches system-level fault tolerance requirements without hardware change. |
| Sequencing & Tracking | TRACK_EN and VP pins support precise power-up/down sequencing with external masters or other IR38060s-meets JEDEC JESD88 timing for multi-rail SoCs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP8765GQ-Z (Monolithic Power) | 6 A, 1.8 V fixed, no PMBus; analog-only with 0.8% ref accuracy and 500 kHz Fsw | Lacks telemetry and digital configuration-suitable only where firmware integration is impractical | Select when cost sensitivity outweighs need for runtime telemetry or field updates. |
| TPS546B24RVFT (TI) | 6 A, 1.8 V programmable, PMBus v1.3 compliant, 0.5% ref, but 4 mm × 5 mm QFN and higher quiescent current (12 mA) | Supports AVSBus for adaptive voltage scaling-better for dynamic voltage scaling in ASICs | Choose when AVSBus compatibility or smaller footprint is prioritized over Infineon's thermal performance (θJ-PCB = 2 °C/W). |
Compared with MP8765GQ-Z and TPS546B24RVFT, IR38060MGM18TRP uniquely combines pre-programmed 1.8 V/607 kHz operation, true differential remote sensing, and sub-1% reference accuracy in a thermally optimized 5×6 mm PQFN-making it optimal for space-constrained, high-reliability server and telecom PoL deployments.

FAQ
Is IR38060MGM18TRP pin-compatible with other IR38060 variants?
Yes-IR38060MGM18TRP shares identical 26-pin PQFN package and pinout with all IR38060 variants (e.g., MTRPBF, MGM10TRP). Only OTP-programmed parameters differ: output voltage (1.8 V), switching frequency (607 kHz), and default PMBus address. No PCB redesign is needed when swapping pre-configured versions.
Does IR38060MGM18TRP require external programming to operate at 1.8 V?
No-IR38060MGM18TRP ships with 1.8 V output voltage and 607 kHz switching frequency permanently programmed in one-time-programmable (OTP) memory. It operates immediately upon power-up with no PMBus initialization, though digital configuration remains available for advanced features like telemetry and fault logging.
What is the role of the P1V8 pin, and how must it be decoupled?
P1V8 supplies the internal digital logic block and must be decoupled with ≥2.2 µF ceramic capacitance to PGND; 10 µF is recommended. This rail powers the PMBus interface, ADCs, and status registers. Failure to adequately decouple causes communication errors or erratic telemetry readings, especially during rapid load transients.
Can IR38060MGM18TRP be used without connecting the PMBus lines (SCL/SDA/SALERT)?
Yes-IR38060MGM18TRP defaults to analog mode when ADDR pin is floating and SCL/SDA are unconnected. In this mode, it delivers regulated 1.8 V output with analog telemetry (IMON, TMON, PGOOD) and retains all protection features (OCP, OVP, OTP). No pull-ups or external logic are required for basic operation.
