Product details
Overview
IP2003ATRPBF from Infineon Technologies is a high-current, integrated MOSFET driver with dead-time control for synchronous buck converters. It delivers up to 40 A output current at 1.3 V output, supports 300–1000 kHz switching frequency, and integrates PRDY power-ready signaling with 4.4 V UVLO threshold. It is used in server VRMs and AI accelerator power delivery where compact, thermally robust DC-DC regulation is required.
For engineers reviewing the IP2003ATRPBF datasheet, IP2003ATRPBF pinout, IP2003ATRPBF application, or IP2003ATRPBF equivalent, key selection criteria include its LGA-10 package thermal performance, 10 µA shutdown quiescent current, 63 ns turn-on delay at 40 A, and dual VSWS pins requiring external shorting for internal gate drive calibration.
Technical Context
The IP2003ATRPBF integrates dual N-channel MOSFET drivers with adaptive dead-time control to prevent shoot-through in high-frequency synchronous buck topologies. It features an internal power block with integrated high-side and low-side FETs, driven by a TTL-compatible PWM input and enabled via a logic-controlled ENABLE pin.
Its PRDY pin provides real-time power-good status based on both ENABLE state and VDD voltage (4.4 V typical UVLO), while the VSW node connects directly to the output inductor and PGND ties to bulk capacitor ground. The VSWS1/VSWS2 pins are internally floating and must be externally shorted per layout guidelines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 40 A RMS - supports high-density CPU/GPU core rail delivery without external phase interleaving |
| Switching Frequency | 300–1000 kHz - enables optimization between inductor size and conduction loss in VRM designs |
| Turn-On Delay | 63 ns typ. at 40 A - ensures precise timing alignment for sub-100 ns critical timing margins |
| VDD UVLO Threshold | 4.4 V typ. with 150 mV hysteresis - prevents erratic operation during brown-out conditions |
| Shutdown Quiescent Current | 10 µA at VDD = 5 V - minimizes standby power in multi-rail power management systems |
| PRDY Drive Capability | 10 mA source / 1 mA sink - directly interfaces with PMIC sequencers or FPGA power-good inputs |
| Input Voltage Range | 3.0–13.2 V - accommodates 5 V, 12 V, and hybrid input rails in compute and networking equipment |
Pinout & Package
LGA-10 package (9.00 × 11.00 mm, 0.635 mm height) with exposed thermal pad; designed for bottom-side reflow and PCB copper thermal spreading.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VDD | Internal circuit supply | 5 V nominal bias rail; decoupling required within 2 mm of pin |
| 2 ENABLE | Logic enable control | Active-high TTL input; forces PRDY low and disables drivers when low |
| 3 PWM | Gate drive command input | TTL-level signal controlling high-side/low-side switching sequence |
| 4 PRDY | Power-ready status output | Open-drain compatible; asserts high only when ENABLE = high AND VDD ≥ 4.4 V |
| 5,7 PGND | Power ground return | Dual connection points for low-inductance return path to bulk capacitors |
| 6 VSW | Switching node | Connects to output inductor; carries full AC ripple current and high dv/dt |
| 8 VIN | Main input power | 3–13.2 V input; requires local 10–100 µF ceramic bypassing |
| 9,10 VSWS1/VSWS2 | Internal gate drive calibration nodes | Floating internal terminals; must be shorted externally per layout spec |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current synchronous buck driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IR35201MTRPBF | Multi-phase controller (not integrated driver); requires external DrMOS; supports up to 6 phases | Used in higher-current (>100 A), multi-phase VRMs where phase interleaving is mandatory | Select when system-level current exceeds 40 A per phase or when digital PMBus configuration is required |
| MP87653GL-Z | Monolithic 40 A buck converter (integrated inductor not present); 2.5 V–18 V input; no PRDY pin | Suitable for space-constrained industrial SMPS where board-level inductor integration is acceptable | Select when simplified BOM and reduced layout risk outweigh need for PRDY sequencing and thermal monitoring |
Compared with IR35201MTRPBF and MP87653GL-Z, the IP2003ATRPBF uniquely combines single-phase 40 A capability, PRDY status signaling, and LGA thermal performance in a driver-only form factor-making it optimal for compact, thermally constrained, single-rail applications where discrete FET control and timing precision are critical.

FAQ
What is the required PCB layout practice for VSWS1 and VSWS2 pins?
The VSWS1 and VSWS2 pins are internally floating and designated for internal gate drive calibration. Per Infineon's layout guidelines, they must be shorted together externally using a low-inductance trace or direct solder bridge. Failure to short them results in undefined gate drive behavior and potential shoot-through risk.
Does IP2003ATRPBF require external bootstrap capacitors?
No. The IP2003ATRPBF does not use a bootstrap architecture; it employs a charge-pump-based high-side driver that operates from the VDD rail. External bootstrap components are unnecessary, simplifying layout and eliminating associated failure modes like capacitor discharge during extended low-duty-cycle operation.
How is PRDY asserted during startup and fault conditions?
PRDY is driven high only when both ENABLE is logic high and VDD exceeds 4.4 V (typical). If ENABLE is low or VDD drops below UVLO threshold, PRDY is actively pulled low. Its 10 mA source capability allows direct connection to FPGA or PMIC power-good inputs without pull-up resistors.
Can IP2003ATRPBF operate at 1.8 V output with 40 A load?
Yes. Electrical specifications confirm operation across 0.8–3.3 V output range at up to 40 A. At 1.8 V output, normalized power loss remains ≤1.08× baseline (per Fig. 5), and safe operating area maintains full 40 A capability at TBLK ≤ 125 °C with appropriate PCB copper area and airflow.
