Product details
Overview
IR38060MTRPBF from Infineon Technologies (formerly International Rectifier) is a synchronous buck DC-DC converter with integrated high- and low-side MOSFETs, PMBus/I²C interface, and digital configurability. It delivers up to 6 A output current at 1.2 V from a 12 V input in a 5 mm × 6 mm PQFN package, featuring true differential remote sensing, pre-bias startup, and temperature-compensated overcurrent protection via RDS(on) sensing.
For engineers reviewing the IR38060MTRPBF datasheet, IR38060MTRPBF pinout, IR38060MTRPBF application, or IR38060MTRPBF equivalent, key selection criteria include its 600 kHz fixed switching frequency, internal 1.8 V LDO for digital core, feed-forward line/load regulation, and support for external frequency synchronization - all critical for point-of-load regulation in server, telecom, and FPGA power delivery.
Technical Context
The IR38060 operates as a digitally controlled, single-phase synchronous buck regulator with integrated power stages. Its PMBus interface enables real-time configuration of output voltage (0.5–3.3 V), soft-start time, UVLO thresholds, OVP/OCP trip points, and thermal shutdown limits - all stored in nonvolatile memory.
It implements adaptive gate drive timing, feed-forward compensation for improved transient response, and a dedicated remote sense amplifier with ±0.5% accuracy over temperature. The device supports hiccup-mode short-circuit protection and seamless transition between FCCM and diode emulation modes via the En/FCCM pin.

Key Features
| Feature | Design Value |
|---|---|
| Integrated dual MOSFET power stage | Eliminates discrete high-/low-side FET selection and layout complexity; reduces BOM count by ≥4 components |

| Pre-bias startup capability | Allows safe turn-on into pre-charged output (e.g., hot-swap or multi-rail sequencing) without reverse current |
| Internal 1.8 V LDO | Derives digital core supply from PVin - removes need for external bias rail and associated filtering |
| Feed-forward line regulation | Compensates for input voltage transients in real time, reducing output deviation during PVin step changes |
Applications

IC Role / Device Role / Timing Role: Robust POL converter with 4.5–18 V input range and comprehensive protection (OVLO, UVLO, thermal). Use Value: Internal LDO eliminates external bias supply; hiccup-mode OCP sustains operation after repeated short-circuits on field wiring. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS546B24RVFT | Higher 10 A rating, 3.3 V max VOUT, no internal LDO - requires external 1.8 V bias | Targets higher-current AI accelerators; lacks pre-bias startup and true differential sensing | Select when >6 A output or tighter thermal limits are required; verify external bias design |
| MP8765GQ-Z | 6 A rating, 500 kHz switching, no PMBus - only analog configuration via resistors and pins | Cost-sensitive industrial applications where digital telemetry is unnecessary | Select when PMBus is unused and BOM cost reduction is prioritized over configurability |
Compared with TPS546B24RVFT and MP8765GQ-Z, IR38060MTRPBF uniquely combines PMBus configurability, true remote sensing, and pre-bias startup in a 5×6 mm footprint - making it optimal for space-constrained, digitally managed POL systems requiring reliability under sequencing and fault conditions.

FAQ
Does IR38060MTRPBF require an external Vcc supply?
No. IR38060MTRPBF integrates an internal LDO that generates 1.8 V for its digital core from the PVin input. External Vcc is optional and only needed if the application requires independent bias control - in which case R25 must be removed and Vcc applied externally with R24 installed to short Vin and Vcc pins.
How is overcurrent protection implemented without a sense resistor?
IR38060MTRPBF uses temperature- and bias-compensated RDS(on) sensing on the integrated low-side MOSFET. This method measures voltage drop across the FET's on-resistance during conduction, eliminating external sense resistors while maintaining accuracy across temperature and load conditions.
Can IR38060MTRPBF operate with a pre-biased output?
Yes. The device supports pre-bias startup: it safely turns on into an already charged output without forcing reverse current through the low-side FET. This is essential for hot-swap and multi-rail sequencing applications where output capacitors may retain residual voltage.
What is the function of the Track_En pin?
The Track_En pin enables voltage tracking mode. When pulled to P1V8 (1.8 V), the IR38060 synchronizes its output ramp with a master rail - ensuring proper power-up sequencing for systems with multiple dependent supplies such as DDR memory interfaces.
