Product details
Overview
iP2005CTRPBF from Infineon Technologies (formerly International Rectifier) is a synchronous buck multiphase power block integrating high-side and low-side MOSFETs, gate drivers, and bootstrap circuitry in a single LGA package. It delivers up to 40A continuous output current, operates at switching frequencies up to 1.5MHz, supports input voltages from 2.5V to 13.2V, and is optimized for microprocessor core voltage regulation in multi-phase DC-DC converters.
For engineers reviewing the iP2005CTRPBF datasheet, iP2005CTRPBF pinout, iP2005CTRPBF application, or iP2005CTRPBF equivalent, key selection criteria include its 7.65mm × 7.65mm LGA-2000 footprint, bi-directional current capability, 4.5–7.0V bias supply range, under-voltage lockout, and thermal performance up to 125°C block temperature.
Technical Context
The iP2005CTRPBF implements a fully integrated synchronous buck stage with internal high-side and low-side silicon-based power switches, eliminating external gate drive components. Its LGA interface provides direct PCB-level thermal and electrical connection, supporting high-current, low-duty-cycle operation with minimal board space.
It features independent PWM input and ENABLE control with defined logic thresholds (VIH = 2.0V, VIL = 0.8V), propagation delays (TPDH ≤ 60ns, TPDL ≤ 30ns), and built-in power-on reset (POR) with 4.15V rising threshold and 200mV hysteresis-enabling robust sequencing in multi-phase controller systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 40 A continuous - supports high-current CPU/GPU core rails without external parallel stages |
| Input Voltage Range | 2.5 V to 13.2 V - compatible with 3.3V, 5V, and 12V intermediate bus architectures |
| Switching Frequency | 250 kHz to 1500 kHz - enables compact magnetics and high transient response in VRMs |
| Power Block Loss | 7.8 W typical at 12VIN, 1.3VOUT, 40A, 1MHz - defines thermal design margin and heatsink requirements |
| Bias Supply (VDD) | 4.5 V to 7.0 V - powers internal gate drivers and logic; decoupling must meet fast transient demands |
| Block Temperature Range | −40 °C to +125 °C - specifies maximum junction-equivalent operating temperature for reliability validation |
| On-Time Duty Cycle | Up to 85 % - enables stable regulation down to ~1.1V output with 13.2V input |
Pinout & Package
The iP2005CTRPBF uses a 2000-pad Land Grid Array (LGA) package measuring 7.65 mm × 7.65 mm × 1.66 mm, with thermal pads on the bottom surface for PCB-level heat extraction. Pin assignment follows standard LGA layout per PD-60360 mechanical drawing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | High-side drain input | Main power input node; connects to bulk capacitor and upstream bus; handles full phase current |
| VSW | Switch node | Connection point between high-side and low-side FETs; ties to output inductor; critical for EMI and ringing control |
| PGND | Power ground | Low-side source return path; requires low-inductance copper pour beneath package for current loop integrity |
| VDD | Bias supply input | Powers internal driver and logic; must be locally decoupled with ≥10µF ceramic + bulk capacitance |
| PWM | Pulse-width modulation input | Digital control signal determining duty cycle; 2.0V logic-high threshold ensures noise immunity in dense layouts |
| ENABLE | Enable/disable control | Active-high enable with 100kΩ weak pull-down; used for sequencing and fault shutdown coordination |
Key Features
| Feature | Design Value |
|---|---|
| No derating up to TPCB = 95°C | Enables full 40A output without current reduction in high-ambient industrial or server environments |
| Bi-directional current flow | Supports active current sharing and phase interleaving in multi-phase controllers with reverse conduction capability |
| Optimized for low power loss | 7.8W typical loss at 40A/1.3V/1MHz allows use in thermally constrained 1U server or laptop VRMs |
| LGA interface | Eliminates solder joints for power paths, reducing contact resistance and improving thermal transfer to PCB |
| Under-voltage lockout (UVLO) | Prevents erratic operation during brown-out by disabling output until VDD reaches 3.8V (rising) with 200mV hysteresis |
Applications
| Microprocessor Core Power Supply | Multi-Phase VRM for AI Accelerators |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck power block applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DrMOS IR35201MTRPBF | Integrated current sense, PMBus interface, 30A rating, 5×6mm QFN | Requires digital controller support; lacks bi-directional current capability | Preferred when telemetry, programmability, or tighter current monitoring are required |
| TI CSD97374Q4M | 40A rating, 3.5×4.5mm SON package, higher RDS(on) (1.2mΩ HS / 0.7mΩ LS) | Smaller footprint but higher conduction loss at >35A; no UVLO hysteresis spec | Selected for ultra-compact 2-phase VRMs where thermal headroom exceeds 10°C margin |
Compared with IR35201MTRPBF and CSD97374Q4M, the iP2005CTRPBF offers superior thermal performance at full 40A load, native bi-directional operation for advanced phase control, and a larger LGA thermal interface-making it optimal for high-reliability, analog-controller-based multi-phase systems where digital telemetry is unnecessary.

FAQ
What is the recommended PCB layout for thermal management of the iP2005CTRPBF?
Thermal performance relies on a dedicated 7.65mm × 7.65mm thermal pad on the PCB bottom layer, connected via ≥8 thermal vias (0.3mm diameter, filled or capped) to inner-layer copper planes. The top-side LGA pads require controlled-depth solder paste printing (125µm stencil) and reflow profile matching IPC-J-STD-020, peak 260°C. No thermal compound is needed-the LGA interface conducts heat directly into the board.
Does the iP2005CTRPBF support phase shedding or diode emulation mode?
No. The iP2005CTRPBF operates exclusively in forced continuous conduction mode (FCCM) and does not implement light-load efficiency modes like diode emulation or discontinuous conduction. Its ENABLE pin supports full on/off control, but dynamic phase shedding requires external controller coordination-not internal state machine behavior.
Can the iP2005CTRPBF be used with a 3.3V bias supply?
No. The specified VDD operating range is strictly 4.5V to 7.0V. A 3.3V supply falls below the 3.8V POR rising threshold and will prevent internal gate drivers from activating. Using underspecified VDD risks incomplete turn-on, excessive conduction loss, and potential device latch-up during startup.
How is the Safe Operating Area (SOA) determined for custom board layouts?
The SOA curve in Figure 2 is calibrated for standard JEDEC test boards. For custom layouts, measure PCB temperature (1mm from package edge) and case temperature (top-center of LGA surface) under worst-case load. Plot those values on the SOA graph: the horizontal intercept gives maximum continuous current. Derating is linear between 95°C and 135°C PCB temperature per AN1047 guidelines.
