Infineon Technologies IR38060MGM09TRP

Overview

IR38060MGM09TRP from Infineon Technologies is a digitally configurable, synchronous buck DC-DC converter with integrated MOSFETs and PMBus interface, delivering up to 6 A at 0.9 V output. It operates from a single 5.5–16 V input, features 0.5% reference voltage accuracy, supports 607 kHz fixed switching frequency, and includes true differential remote sensing for precision load regulation in server point-of-load applications.

For engineers reviewing the IR38060MGM09TRP datasheet, IR38060MGM09TRP pinout, IR38060MGM09TRP application, or IR38060MGM09TRP equivalent, key selection criteria include its pre-configured 0.9 V output, thermally compensated current limit, dedicated output voltage sensing protection active during disable, and compatibility with distributed PoL architectures requiring PMBus telemetry and sequencing.

Technical Context

The IR38060 implements a voltage-mode PWM controller with internal LDO biasing (VCC = 4.5–5.5 V), enabling single-supply operation without external bias rails. Its digital control loop supports 66 PMBus commands for real-time configuration of output voltage, switching frequency, overcurrent thresholds, and fault responses - all stored in nonvolatile memory.

It integrates high-side (14–27 mΩ) and low-side (6–12 mΩ) MOSFETs, a bootstrap diode, and a remote sense amplifier with RS+, RS−, and RSo terminals. The device supports both analog mode (via RT/SYNC and EN/FCCM) and digital mode (PMBus), with seamless transition between them without reconfiguration.

Key Specifications

Pinout & Package

IR38060MGM09TRP uses a 26-pin, 5 mm × 6 mm PQFN package with exposed thermal pad (PGND-connected). Pin 1 is PVIN; pins 12, 23, and 25 are PGND; pin 13 is LGND; pin 26 is NC. Thermal resistance θ_J-PCB = 2 °C/W enables high-power density designs.

FAQ

Is IR38060MGM09TRP pin-compatible with other IR38060 variants?

Yes - all IR38060 variants share identical 26-pin PQFN packaging and pinout. The MGMT09TRP differs only in factory-programmed output voltage (0.9 V) and default switching frequency (607 kHz); no hardware changes are required for substitution within the same PCB footprint.

Does IR38060MGM09TRP require PMBus communication to operate?

No - it functions as a standalone analog regulator without any PMBus interaction. The pre-configured 0.9 V output, 607 kHz frequency, and default protection thresholds are active immediately upon enable, with telemetry available via analog pins (IMON, TMON, SALERT) if digital interface is unused.

What is the purpose of the VSNS pin, and how does it differ from FB?

VSNS provides independent overvoltage protection and PGood signaling using a dedicated comparator path that remains active even when EN is low. Unlike FB - which feeds the regulation loop - VSNS monitors output voltage separately for safety-critical fault detection, ensuring fail-safe behavior during startup, shutdown, or controller lockup.

Can IR38060MGM09TRP be used with an external 5 V bias instead of the internal LDO?

Yes - applying 4.5–5.5 V to the VCC pin bypasses the internal LDO, reducing power loss and heat generation. In this mode, Vin pin must still be connected to PVIN (5.5–16 V), and the internal LDO is disabled; VCC becomes the sole bias source for gate drivers and logic.
