Product details

Overview

IR38060MBC01TRP from Infineon Technologies is a digitally configurable, synchronous buck DC/DC converter with integrated MOSFETs and PMBus interface, delivering up to 6 A output current at 0.5–0.875×PV_IN output voltage range, 0.5% reference accuracy, and programmable switching frequency up to 1.5 MHz - deployed in Broadcom SAS34xx–SAS37xx storage controller platforms for precise core voltage regulation.

For engineers reviewing the IR38060MBC01TRP datasheet, IR38060MBC01TRP pinout, IR38060MBC01TRP application, or IR38060MBC01TRP equivalent, key selection considerations include its dual-mode (analog/digital) operation, true differential remote sensing, thermally compensated overcurrent protection, and dedicated P1V8 digital supply rail with internal LDO enabling single 16 V input operation.

Technical Context

The IR38060 implements a voltage-mode PWM controller with integrated high- and low-side MOSFETs (R_DS(on) = 14–27 mΩ / 6–12 mΩ), bootstrap gate drive, and internal 5.5 V LDO for biasing - supporting both analog configuration via RT/SYNC and EN/FCCM pins and full digital control via 400 kHz PMBus interface with 66 supported commands. It features dedicated voltage-sensing protection active even when ENABLE is deasserted.

Its block diagram integrates a remote sense amplifier (RS+, RS−, RSO), thermal monitoring (TMON), output current telemetry (IMON), and fault telemetry (OCSet, SALERT) - all referenced to LGND and PGND separately, with independent UVLO thresholds on PV_IN, V_CC, and EN pins, and junction temperature rating of −40°C to +125°C.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Current	6 A continuous - supports high-current CPU/I/O core rails in SAS host bus adapters without external current sharing.
Output Voltage Range	0.5 V to 0.875×PV_IN - enables adaptive scaling for 1.2 V, 1.0 V, or 0.8 V logic domains from common 12 V intermediate bus.
Reference Accuracy	±0.5% at 25°C (0.45–1.25 V FB range) - ensures tight regulation tolerance for sub-1 V ASIC supplies.
Switching Frequency	225–1650 kHz - adjustable via RT resistor or external clock sync, enabling EMI optimization and inductor size reduction.
Interface Protocol	400 kHz PMBus v1.3 - supports real-time telemetry (VOUT, IOUT, TEMP), sequencing, fault logging, and nonvolatile configuration storage.
Junction Temp Range	−40°C to +125°C - validated for sustained operation in enclosed server/storage enclosures with limited airflow.
Package Thermal Resistance	θ_J-PCB = 2°C/W - enables >5 W power dissipation on standard 2-layer PCBs without heatsink.

Pinout & Package

IR38060MBC01TRP is housed in a thermally enhanced 5 mm × 6 mm PQFN package with exposed thermal pad (PGND-connected), 26-pin layout, and dual ground domains (PGND for power stage, LGND for analog/digital control).

Pin/Terminal	Circuit Role	Design Meaning
PVIN (1)	Main power input for high-side MOSFET	Accepts 1.2–16 V input; requires local 4×22 µF + 0.1 µF ceramic bypassing to adjacent PGND pins.
BOOT (2)	High-side gate driver bootstrap supply	Connects via 0.1 µF capacitor to SW; series 0 Ω or 1 Ω resistor recommended for PV_IN > 12 V.
TRACK_EN# (3)	Tracking enable control input	Pull low to enable voltage tracking; otherwise tie to P1V8 via 100 kΩ for normal operation.
Vsns (5)	OVP and PGOOD sense input	Dedicated overvoltage detection path - remains active even when EN is low, ensuring fail-safe rail monitoring.
RS+ / RS− (10/9)	Differential remote sense inputs	Enable true Kelvin sensing at load; RS+ connects to output, RS− to load ground, rejecting PCB IR drop.
SALERT#/TMON (17)	Open-drain alert / analog temp monitor	Provides junction temperature voltage (0.5 V = 0°C, 10 mV/°C) in analog mode; SMBus ALERT# in digital mode.
SDA/IMON (18)	I²C data / analog current monitor	Outputs voltage proportional to I_OUT (10 mV/A typical) when PMBus disabled; bidirectional SDA when enabled.
ADDR (16)	PMBus address offset resistor terminal	Resistor to LGND sets 7-bit slave address (default 0x70); floating in analog-only applications.

Key Features

Feature	Design Value
Integrated Power Stage	Monolithic 6 A buck regulator with matched top/bottom MOSFETs (14/6 mΩ typ), eliminating external FETs and gate drivers.
Dual-Mode Operation	Runs as fully programmable PMBus device or self-configured analog regulator - no firmware required for basic startup.
Pre-Bias Soft-Start	Enables safe turn-on into pre-biased outputs without reverse current, critical for hot-swap and multi-rail sequencing.
Thermally Compensated OCP	Current limit adjusts with junction temperature to maintain consistent trip point across −40°C to +125°C operating range.
Dedicated P1V8 Rail	On-chip 1.8 V LDO powers digital logic and PMBus interface independently - decoupled from main V_CC and immune to analog noise.

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)	4 A max output, no PMBus, only I²C-compatible register set; lacks remote sense amplifier and TRACK_EN# pin.	Targeted at cost-sensitive industrial PoL where telemetry and sequencing are not required.	Select when digital configurability and true differential sensing are unnecessary and board space allows larger inductor.
TPS546B24RVFT (TI)	6 A, PMBus v1.3, but uses 4 mm × 5 mm QFN; lacks internal LDO - requires external 5 V bias rail.	Preferred in TI-centric designs with existing 5 V bias infrastructure and tighter board area constraints.	Choose if leveraging TI's Fusion Digital Power Designer toolchain and existing 5 V supply distribution.

Compared with MP8770GQ-Z and TPS546B24RVFT, the IR38060MBC01TRP uniquely combines single-supply 16 V operation (via internal LDO), true differential remote sensing, and dedicated P1V8 rail - making it optimal for high-integrity storage and telecom applications where rail integrity and telemetry fidelity are non-negotiable.

FAQ

What is the default PMBus address for IR38060MBC01TRP?

The default 7-bit PMBus address is 0x70, set by leaving the ADDR pin floating. When a resistor is connected from ADDR to LGND, the address shifts per the datasheet's offset table - e.g., 10 kΩ yields 0x71. Address configuration must occur before first communication, as the value is latched at power-up and stored in nonvolatile memory.

Can IR38060MBC01TRP operate without PMBus programming?

Yes - it defaults to analog mode with factory-programmed parameters: 607 kHz switching frequency, 0.5 V output (for MBC01 variant), and standard OCP/OTP thresholds. All control pins (EN/FCCM, RT/SYNC, TRACK_EN#) remain functional, and analog telemetry (IMON, TMON, PGOOD) is available without digital initialization.

How does the internal LDO enable single 16 V input operation?

The internal LDO accepts 5.5–16 V on the VIN pin and regulates it to a stable 5.5 V VCC rail for gate drivers and analog circuitry. This eliminates the need for an external bias supply, allowing full functionality - including MOSFET drive and PMBus interface - from a single intermediate bus voltage.

What is the purpose of the Vsns pin separate from FB and RS+?

Vsns provides dedicated overvoltage protection and PGOOD generation independent of the feedback loop. It monitors output voltage directly and asserts PGOOD or triggers shutdown within 500 ns if V_OUT exceeds threshold - even if the FB loop is disabled or compromised, ensuring hardware-level rail safety.
