Product details
Overview
IP2004TR from Infineon Technologies is a synchronous buck DC-DC power stage IC integrating high- and low-side MOSFETs, driver, and bootstrap circuit in a single LGA package. It delivers up to 40 A continuous output current, supports adjustable output voltage down to 0.5 V, and operates with input voltage range of 4.5 V to 16 V. It is designed for high-density server VRMs and AI accelerator power delivery.
For engineers reviewing the IP2004TR datasheet, IP2004TR pinout, IP2004TR application, or IP2004TR equivalent, key selection criteria include its integrated dual-MOSFET architecture, 40 A thermal-current rating, 0.5–5.5 V output adjustability, and LGA-17 (5 mm × 6 mm) package with exposed thermal pad for board-level thermal management.
Technical Context
The IP2004TR integrates a 3.2 mΩ high-side and 1.8 mΩ low-side silicon MOSFET pair with adaptive gate drive and integrated bootstrap diode. It features internal current-sense amplifier output (IMON) for real-time load monitoring and supports external PWM controller feedback via VSENSE pin with ±1% reference accuracy.
It implements thermal shutdown at 150 °C and overcurrent protection with cycle-by-cycle limiting. The device requires no external bootstrap capacitor due to on-die charge pump, simplifying layout while maintaining reliable high-side FET turn-on across duty cycles.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current synchronous buck power stage applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI CSD97395Q4M | Higher RDS(on) (3.8 mΩ HS / 2.2 mΩ LS); 35 A rated; QFN-12 package | Lower thermal performance margin in constrained airflow environments | Preferred where QFN footprint compatibility exists and 35 A suffices |
| ON Semi ISL99390 | Supports 40 A but requires external bootstrap capacitor; 1.2 V minimum output | Lacks IMON output and has higher minimum VOUT, limiting use in sub-1 V AI rails | Selected when legacy design reuse favors SOIC-8 footprint and IMON not required |
Compared with CSD97395Q4M and ISL99390, the IP2004TR offers superior thermal resistance, integrated bootstrap charge pump, and full 0.5 V output capability - making it optimal for next-gen AI/ML hardware demanding compact, high-accuracy, low-voltage power delivery.

FAQ
What is the recommended PCB layout for thermal management of the IP2004TR?
The IP2004TR requires direct soldering of its exposed thermal pad (EP) to a minimum 200 mm² internal or bottom-layer copper pour with ≥6 thermal vias (0.3 mm diameter, spaced ≤1 mm apart). Avoid splitting the PGND plane under the device; connect all PGND pins and EP to a solid, low-impedance ground plane to ensure <15 °C temperature rise at 40 A.
Does the IP2004TR support parallel operation for higher current?
Yes - the IP2004TR supports current-sharing in parallel configurations using its IMON output. Connect IMON pins together through 10 kΩ resistors and feed into a common current-summing op-amp to generate a shared current-sense signal for master-slave phase control in multi-phase VRMs.
Can the IP2004TR operate with a 3.3 V input supply?
No - the IP2004TR has a minimum input voltage of 4.5 V due to internal gate-drive voltage requirements and UVLO threshold. Operation below 4.5 V will result in EN deactivation and automatic shutdown; it is not rated for 3.3 V intermediate bus use.
Is an external bootstrap capacitor required for the IP2004TR?
No - the IP2004TR integrates a charge-pump-based bootstrap circuit that eliminates the need for an external bootstrap capacitor or diode. This reduces component count, improves reliability, and avoids layout sensitivity associated with discrete bootstrap networks.
