UCC2541PWP

DC DC Switching Controllers Overview

The UCC2541PWP is a voltage-mode synchronous-buck PWM controller designed for high-current output converters delivering 30 A or higher. It operates with a supply voltage range of 8.5V to 35V and supports a switching frequency of 300kHz. The device features a 20-HTSSOP package, enabling surface-mount installation. It provides positive output configuration with one output stage. Key control characteristics include enable, slope compensation, reset, soft-start, and tracking capabilities.

DC DC Switching Controllers Feature Summary

• Supports synchronous rectification for improved efficiency in high-current applications
• Integrates clock synchronization functionality for multi-phase systems
• Includes comprehensive protection and control features such as soft-start and tracking

DC DC Switching Controllers Applications

• High-efficiency synchronous buck converter designs
• Power supplies requiring output currents of 30 A or higher
• Multi-phase power distribution architectures

DC DC Switching Controllers Procurement Notes

Verify the specific package variant, as the UCC2541 family includes different pinouts and thermal characteristics across QFN and HTSSOP options. Confirm that the 20-pin HTSSOP form factor aligns with your PCB layout constraints. Check current availability status, as this component may be subject to lifecycle changes or obsolescence notices from Texas Instruments.

DC DC Switching Controllers Selection Notes

Select this controller when designing for high-current loads exceeding 30 A where voltage-mode control is preferred. Ensure the external components support the 300kHz switching frequency and the input voltage stays within the 8.5V to 35V range. Consider the thermal performance of the 20-HTSSOP package for your specific power dissipation requirements.

DC DC Switching Controllers Part Context

The UCC2541PWP belongs to the UCC2541 family of high-efficiency synchronous buck PWM controllers. This series is engineered for applications demanding significant output current capabilities. The PWP suffix specifically denotes the 20-pin PowerTSSOP/HTSSOP package option, distinguishing it from other variants like the RHBR which uses a QFN package.

DC DC Switching Controllers Replacement Considerations

Direct replacements must match the 20-pin HTSSOP package and synchronous buck topology. Verify compatibility with existing board layouts due to potential pinout differences between package types within the same family.
