Product details
Overview
IP2034TRPBF from Infineon Technologies is a synchronous buck DC-DC controller IC designed for high-current, high-efficiency point-of-load (POL) regulation in server and telecom power supplies. It supports adjustable output voltage from 0.6 V to 5.5 V, delivers up to 40 A via external MOSFETs, operates with input voltage range 4.5 V to 18 V, and features integrated 5-V gate driver with 2-A peak sink/source capability for dual N-channel FETs.
For engineers reviewing the IP2034TRPBF datasheet, IP2034TRPBF pinout, IP2034TRPBF application, or IP2034TRPBF equivalent, key selection criteria include its programmable switching frequency (100 kHz–1 MHz), adaptive on-time control architecture, differential remote sensing, overcurrent protection with cycle-by-cycle limiting, and thermal shutdown with hysteresis.
Technical Context
The IP2034TRPBF implements adaptive on-time (AOT) control with internal compensation, enabling fast transient response without external loop components. It integrates a precision 0.6-V reference with ±1% tolerance over temperature and load, and supports both single- and dual-phase configurations via SYNC pin synchronization.
Its current-sense architecture uses low-side RDS(on) sensing or discrete sense-resistor inputs, with configurable blanking time and gain. The device includes dedicated EN/UVLO threshold (0.7 V typical), power-good signal with adjustable delay, and I2C-compatible SMBus interface for telemetry readback (VOUT, IOUT, temperature).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Topology | Synchronous buck controller - requires external high- and low-side N-MOSFETs for full power stage implementation. |
| Output Current | Up to 40 A - scalable via parallel phase configuration using multiple controllers. |
| Input Voltage Range | 4.5 V to 18 V - compatible with 5 V, 12 V, and hybrid intermediate bus architectures. |
| Output Voltage Range | 0.6 V to 5.5 V - set by external resistor divider; 0.6 V reference enables sub-1 V core rail support. |
| Switching Frequency | 100 kHz to 1 MHz - user-programmable via RT resistor; higher frequencies reduce output filter size. |
| Control Method | Adaptive on-time (AOT) - provides inherent stability, no external compensation required. |

Pinout & Package
IP2034TRPBF is housed in a thermally enhanced 32-pin QFN package (5 mm × 5 mm, 0.5 mm pitch) with exposed thermal pad for PCB-level heat dissipation.

|---|---|---|
| VIN | Primary power input | Supplies internal bias and gate driver; connects to 4.5–18 V intermediate bus. |
| VDD5 | 5-V regulated output | Internal LDO output powering logic and gate driver; can supply external circuitry up to 50 mA. |
| PHASE | High-side FET source node | Connects to source of high-side MOSFET; used for bootstrap capacitor charging and voltage sensing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP2960A from Monolithic Power Systems | Fixed 600-kHz switching frequency; no SMBus telemetry; uses voltage-mode control with external compensation. | Lacks real-time current/temperature telemetry and adaptive on-time transient performance. | Preferred where cost sensitivity outweighs telemetry needs and simpler loop tuning is acceptable. |
| ISL95812 from Renesas | Supports Intel VR13.HC only; fixed 0.6-V reference; no programmable soft-start; no thermal hysteresis. | Designed specifically for Intel CPU platforms; lacks flexibility for non-Intel or multi-rail systems. | Best suited for legacy Intel server designs requiring strict VR13.HC compliance without customization. |
Compared with MP2960A and ISL95812, IP2034TRPBF offers superior transient response via adaptive on-time control, full SMBus telemetry for predictive maintenance, and broader input/output flexibility-making it optimal for next-gen AI and 5G infrastructure where observability and dynamic load handling are critical.

FAQ
What external components are mandatory for IP2034TRPBF operation?
The IP2034TRPBF requires an external bootstrap capacitor (0.1 µF ceramic between BOOT and PHASE), feedback resistor divider (for VOUT setting), input bulk capacitor (≥100 µF), output LC filter (inductor + bulk + ceramic capacitors), and gate resistors for UGATE/LGATE. No external compensation network is needed due to adaptive on-time control.
Does IP2034TRPBF support multiphase interleaving?
Yes - IP2034TRPBF supports two-phase interleaving via the SYNC pin. When configured as master, it generates a clock signal; as slave, it synchronizes switching to minimize input ripple. Phase offset is fixed at 180°, and up to two controllers can be paralleled for 80-A total output with reduced thermal stress.
Can IP2034TRPBF operate with 3.3-V input?
No - IP2034TRPBF has a minimum input voltage of 4.5 V. Operation below this threshold disables the internal bias regulator and gate drivers. For 3.3-V input applications, a pre-regulator stage or alternative controller with lower VIN rating (e.g., TPS546D24) is required.
How is overcurrent protection implemented?
Overcurrent protection uses cycle-by-cycle current limiting based on sensed voltage across the low-side MOSFET's RDS(on) or a discrete sense resistor. The ISEN pin detects differential voltage; when exceeding the internal threshold (typically 25 mV), the high-side switch is disabled for that cycle. Hiccup-mode recovery occurs after a fixed timeout if fault persists.
