IRU3037ACSTRPBF

DC DC Switching Controllers Overview

The IRU3037ACSTRPBF is a synchronous PWM controller IC designed for low-cost DC-DC converter applications. It supports Buck and Boost topologies with a switching frequency of 400 kHz. The device features a maximum duty cycle of 90% and an output voltage of 800 mV. It accommodates an output current of 15 A and operates within a temperature range of 0 C to +70 C. Packaged in an 8-pin TSSOP/SOIC format, it serves as a driver for board-level power management.

DC DC Switching Controllers Feature Summary

• Supports synchronous rectification for improved efficiency in buck and boost configurations
• Operates at a fixed switching frequency of 400 kHz
• Designed for low-voltage ASIC power supply requirements

DC DC Switching Controllers Applications

• On-board DC-to-DC conversion for ASIC products
• Low voltage power regulation systems requiring currents exceeding 3A
• Synchronous buck regulator implementations

DC DC Switching Controllers Procurement Notes

Verify component authenticity through authorized Infineon channels or certified distributors. Confirm the specific suffix matches the required package and tape/reel specifications. Check for End-of-Life status notifications, as discontinuation notices may apply to this series. Ensure compliance with RoHS standards and moisture sensitivity levels prior to assembly.

DC DC Switching Controllers Selection Notes

Select this controller when designing synchronous converters for ASICs needing sub-2V outputs and high current. Compare against linear regulators where input voltages are 5V or 3.3V to address thermal loss issues. Consider the 400 kHz frequency for passive component size optimization. Verify that the 15 A output capability aligns with load requirements.

DC DC Switching Controllers Part Context

This part belongs to the IRU3037 family of switching controllers from Infineon Technologies (formerly International Rectifier). Variants such as IRU3037CSTR and IRU3037CFTR exist with differing frequencies or packages. The ACSTRPBF designation indicates a specific tape-and-reel packaging configuration for automated assembly.

DC DC Switching Controllers Replacement Considerations

Public confirmed substitutes include IRU3037CSPBF, IRU3037ACFPBF, and IRU3037CFPBF. These variants share similar functional descriptions but may differ in switching frequency or package type. Verify pinout compatibility before substitution.
