TPS5618PWP

Special Purpose Regulators Overview

The TPS5618PWP is a synchronous buck controller manufactured by Texas Instruments. It operates with an input voltage range of 11.4 V to 13 V and provides a fixed output voltage of 1.8 V at a maximum output current of 2 A. The device supports switching frequencies up to 1 MHz and features a duty cycle capability of up to 98%. It is housed in a 16-PowerTSSOP package and functions within a temperature range of -40°C to +125°C.

Special Purpose Regulators Feature Summary

• Synchronous buck control topology for high efficiency
• Integrated soft-start functionality
• Frequency control and current limit protection

Special Purpose Regulators Applications

• Point-of-load regulation for industrial systems
• Power supply stages for embedded controllers

Special Purpose Regulators Procurement Notes

Verify the specific suffix against official documentation, as ordering codes may indicate variations in packaging or temperature rating that do not alter the core electrical function. Confirm RoHS compliance status through the manufacturer's datasheet rather than distributor summaries. Ensure the selected variant matches the required thermal performance for the intended operating environment.

Special Purpose Regulators Selection Notes

Select this component when a fixed 1.8 V output is required from a narrow 11.4 V to 13 V input rail. The synchronous design suits applications demanding higher efficiency than standard PWM controllers. Consider the 16-PowerTSSOP package for thermal management needs and verify that the 2 A current capability aligns with the load requirements.

Special Purpose Regulators Part Context

This part belongs to the TPS5618 series of synchronous buck controllers from Texas Instruments. These devices are designed for applications requiring efficient step-down conversion with integrated power stage drivers. The series typically offers robust protection features and flexible configuration options for various industrial and commercial power architectures.

Special Purpose Regulators Replacement Considerations

Consult the TI product selection guide for direct replacements within the synchronous buck controller family. Verify pin compatibility and thermal characteristics before substituting with other 16-PowerTSSOP packages.
