TPS40057PWPG4

DC DC Switching Controllers Overview

The TPS40057PWPG4 is a synchronous buck DC-DC switching controller manufactured by Texas Instruments. It operates with a maximum switching frequency of 1MHz and supports a supply voltage range of 8V to 40V. The device features a maximum duty cycle of 94% and includes integrated clock synchronization capabilities. Designed for surface-mount installation, it utilizes a 16-HTSSOP package and functions within an operating temperature range of -40°C to 85°C.

DC DC Switching Controllers Feature Summary

• Supports synchronous rectification for improved efficiency in buck converter applications
• Enables precise timing alignment through dedicated clock synchronization functionality
• Integrates comprehensive control features including current limiting, enable control, frequency adjustment, and soft-start

DC DC Switching Controllers Applications

• High-efficiency point-of-load (POL) power conversion modules
• Industrial equipment requiring robust wide-input voltage regulation
• Telecommunications infrastructure power distribution systems

DC DC Switching Controllers Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS3 compliance and moisture sensitivity level 2 handling requirements during storage and assembly processes. Ensure compatibility with existing thermal management solutions given the HTSSOP package constraints.

DC DC Switching Controllers Selection Notes

Evaluate input voltage ranges against the specified 8V to 40V operational window. Consider the 16-pin PowerTSSOP footprint for PCB layout optimization. Assess thermal performance requirements relative to the -40°C to 85°C ambient temperature specification. Verify that system timing demands align with the available clock synchronization interface.

DC DC Switching Controllers Part Context

This component belongs to the TPS4005x family of high-performance synchronous buck controllers from Texas Instruments. It shares architectural similarities with related models like the TPS40054 and TPS40055, offering consistent control logic across the series while maintaining specific electrical characteristics tailored for mid-range input voltage applications.

DC DC Switching Controllers Replacement Considerations

The TPS40057PWP serves as the non-green equivalent alternative. Designers should verify pinout compatibility and ensure that environmental compliance requirements do not mandate the original G4 suffix version.
