Infineon Technologies IP2003APBF

Overview

IP2003APBF from Infineon Technologies is a high-current, integrated synchronous buck MOSFET driver with dead-time control and power-ready status signaling. It delivers up to 40 A output current at 1.3 V output, supports 300–1000 kHz switching frequency, and features under-voltage lockout (UVLO) with 4.4 V start threshold and 150 mV hysteresis. It is used in point-of-load (POL) DC-DC converters for server VRMs and telecom power modules.

For engineers reviewing the IP2003APBF datasheet, IP2003APBF pinout, IP2003APBF application, or IP2003APBF equivalent, key selection criteria include its 10-pin LGA package, dual floating VSWS pins requiring external shorting, PRDY logic-level output with 10 mA source/1 mA sink capability, and thermal-aware safe operating area (SOA) defined up to 125 °C block temperature.

Technical Context

The IP2003APBF integrates gate drivers for high-side and low-side N-channel MOSFETs in a single LGA package, with internal dead-time generation to prevent shoot-through. Its PWM input accepts TTL-level signals, and ENABLE controls full device activation while reducing quiescent current to 10 µA in shutdown.

PRDY reflects both ENABLE state and VDD health via a comparator referenced to 4.4 V typical UVLO threshold. The device operates across 3.0–13.2 V input range and regulates output voltage down to 0.8 V, with power loss tightly characterized (9.4 W typical at VIN=12 V, VOUT=1.3 V, fSW=1 MHz).

Key Specifications

Pinout & Package

IP2003APBF uses a 10-pin LGA (Land Grid Array) package with 0.635 mm pitch, 9.00 × 11.00 mm body, and exposed thermal pad. Pin 1 is marked by corner ID; orientation follows JEDEC MO-222 SPP-010 land pattern. Thermal vias under the pad are required for effective heat dissipation.

Compared with IR35201MTRPBF and MP8765GQ-Z, IP2003APBF uniquely balances integration (driver + dead time + PRDY) with discrete FET flexibility and thermal manageability-making it optimal for single-phase, high-current, thermally constrained POL designs where status visibility and layout control are essential.

FAQ

What is the function of the VSWS1 and VSWS2 pins?

VSWS1 and VSWS2 are internal floating nodes used for level-shifting within the high-side driver circuitry. They serve no external signal function and must be shorted together externally using a low-inductance trace. No passive components or connections to other nets are permitted-this short is mandatory per Infineon's layout guidelines.

Can IP2003APBF operate with input voltages below 4.6 V?

Yes-IP2003APBF supports VIN as low as 3.0 V, but VDD must remain ≥4.6 V (min recommended) for proper logic and driver operation. If VIN drops below ~4.6 V, an external LDO or charge pump is required to maintain VDD, since the internal regulator does not bootstrap from VIN below that threshold.

How is PRDY used in power sequencing?

PRDY serves as a combined "power good" signal: it goes high only when both ENABLE is asserted *and* VDD exceeds 4.4 V (typical UVLO threshold). This allows downstream devices (e.g., FPGAs or processors) to safely initiate configuration only after stable bias and enable conditions are met-eliminating need for separate supervisor ICs in many designs.

What PCB layout practices are critical for thermal performance?

Three practices are essential: (1) Place ≥6 X 10 µF X5R/X7R ceramic capacitors directly adjacent to VIN, PGND, and VSW pins; (2) Use ≥8 thermal vias (0.3 mm diameter, 0.6 mm pitch) under the exposed pad, connected to an internal solid ground plane; (3) Route high-current PGND and VSW traces as wide, short, and overlapping layers to minimize loop inductance-per IR AN-1029a guidelines.
