Product details
Overview
IR38062MTRPBF from Infineon Technologies is a digitally configurable, synchronous buck DC-DC regulator with integrated MOSFETs and PMBus/I²C interface, delivering up to 15 A output current at 0.5–0.875×PVIN, operating from 5.5–21 V input, and featuring ±0.5% reference voltage accuracy for server point-of-load power delivery.
For engineers reviewing the IR38062MTRPBF datasheet, IR38062MTRPBF pinout, IR38062MTRPBF application, or IR38062MTRPBF equivalent, key selection considerations include its dual-mode operation (analog/digital), thermally compensated overcurrent protection, remote differential sensing, programmable switching frequency up to 1.5 MHz, and dedicated PGood and thermal telemetry via analog pins in non-PMBus configurations.
Technical Context
The IR38062 implements a voltage-mode PWM controller with internal LDO biasing, supporting both analog configuration (via RT/Sync, EN/FCCM, ADDR resistors) and full digital control via 66 PMBus commands-including real-time telemetry of output voltage, current, and temperature. Its block diagram integrates gate drivers, bootstrap diode, and remote sense amplifier with true differential inputs (RS+, RS−).
It features dual ground domains (PGND/LGND), dedicated OVP sensing on Vsns, pre-bias soft-start, and sequencing/tracking capability via Track_EN and Vp pins. The device maintains active output voltage monitoring even when disabled (Enable low), and supports smooth external clock synchronization across 225–1650 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 15 A continuous - supports high-current CPU/GPU core rails in dense server PCB layouts |
| Input Voltage Range | 5.5 V to 21 V - single-supply operation enabled by internal LDO, eliminating need for auxiliary bias rail |
| Output Voltage Range | 0.5 V to 0.875×PVIN - enables adaptive scaling for modern low-voltage processors |
| Reference Accuracy | ±0.5% at 0–85°C - ensures tight regulation tolerance without external calibration |
| Switching Frequency | 225 kHz to 1.5 MHz - adjustable via RT resistor or PMBus; higher frequencies reduce output filter size |
| Junction Temp Range | −40°C to +125°C - qualified for industrial and telecom base station thermal environments |
| Thermal Resistance | θJ-PCB = 2.05°C/W - optimized 5 mm × 7 mm PQFN package enables >10 W/cm² power density |
Pinout & Package
IR38062MTRPBF is housed in a thermally enhanced 5 mm × 7 mm PQFN package with exposed thermal pad (pin 27), 26-pin layout, and internally connected pins 23/26. PGND (pins 12, 25) and LGND (pin 13) are separated to minimize noise coupling between power and signal grounds.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PVIN (1) | Main power stage input | Connects directly to bulk input capacitors; requires low-ESL/ESR decoupling near pin for EMI suppression |
| Boot (2) | High-side driver bootstrap supply | Requires 0.1 µF ceramic cap to SW; series resistor needed for PVIN > 16 V to limit boot diode stress |
| Track_EN# (3) | Tracking enable control | Pull low to activate sequencing; otherwise tie to P1V8 via 100 kΩ to disable tracking |
| Vsns (5) | OVP and PGood sensing node | Dedicated overvoltage protection path independent of FB loop; remains active during shutdown |
| FB (6) | Error amplifier inverting input | Accepts direct connection to output or remote sense amplifier output for precision regulation |
| RT/Sync (14) | Frequency setting / sync input | Resistor-to-GND sets fSW in analog mode; accepts external clock for phase alignment in multi-rail systems |
| EN/FCCM (15) | Enable / forced CCM mode | Logic-high enables regulation; <3.1 V forces continuous conduction mode for light-load stability |
| SALERT#/TMON (17) | SMBus alert / analog temp monitor | Open-drain alert output; provides linear voltage proportional to TJ when SMBus inactive |
| SDA/IMON (18) | Data I/O / analog current monitor | Provides voltage proportional to IOUT (0–2 V per 15 A) without PMBus communication |
| SCL/OCSet (19) | Clock input / analog OCP threshold | Configures overcurrent trip level via resistor divider when PMBus not used |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Power Stage | Top/bottom MOSFETs with RDS(on) = 2.7 mΩ / 1.11 mΩ reduce BOM count and improve efficiency at 15 A |
| Dual-Mode Operation | Full PMBus configurability or plug-and-play analog mode with no firmware required |
| True Differential Remote Sensing | RS+/RS− inputs reject PCB trace IR drop, enabling ±0.5% load regulation at point-of-load |
| Pre-Bias Soft-Start | Allows safe startup into pre-charged output capacitors-critical for hot-swap and multi-rail sequencing |
| Thermally Compensated OCL | Current limit adjusts with junction temperature to maintain consistent fault margin across −40°C to +125°C |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP8770GQ-Z (Monolithic Power) | 12 A rated, no PMBus, only analog interface; lacks remote sensing and tracking pins | Suitable for cost-sensitive, fixed-output applications without telemetry or sequencing needs | Select when digital control and multi-rail coordination are unnecessary and board space allows larger external MOSFETs |
| TPS546D24RQF (Texas Instruments) | 15 A, PMBus v1.3 compliant, supports AVSBus for dynamic voltage scaling; requires external boot capacitor | Better suited for AVS-enabled processors (e.g., Xilinx Versal) requiring fine-grained voltage margining | Choose when system-level voltage margining and AVS protocol integration outweigh IR38062's integrated boot diode advantage |
Compared with MP8770GQ-Z and TPS546D24RQF, the IR38062MTRPBF uniquely combines integrated MOSFETs, true differential remote sensing, and active OVP monitoring during disable-making it optimal for compact, thermally constrained, and safety-critical PoL designs where analog fallback and robust fault coverage are mandatory.

FAQ
Can IR38062MTRPBF operate without PMBus communication?
Yes. It functions as a fully featured analog buck regulator using resistor-based configuration (RT/Sync, ADDR, EN/FCCM). All critical functions-including output voltage setting, frequency selection, overcurrent threshold, and thermal/current telemetry via analog pins (SALERT#/TMON, SDA/IMON)-remain operational without PMBus.
What is the minimum output voltage achievable with IR38062MTRPBF?
The minimum output voltage is 0.5 V, specified across the full operating temperature range (−40°C to +125°C) and input voltage range (5.5–21 V). This is enforced by internal reference architecture and validated in electrical characteristics tables under "Reference Voltage Accuracy".
How does the IR38062MTRPBF handle pre-biased outputs during startup?
It implements hardware-based pre-bias start-up: the controller detects existing output voltage before enabling switching, disables bottom-FET discharge, and ramps up duty cycle only after confirming safe conditions-preventing reverse current flow and ensuring monotonic rise even into pre-charged loads.
Is external bootstrap diode required for IR38062MTRPBF?
No. The device integrates a bootstrap diode within the PQFN package. Only an external 0.1 µF ceramic capacitor between Boot and SW pins is required. For PVIN > 16 V, a small series resistor (1–4.02 Ω) is recommended to limit peak boot diode current and improve reliability.
