TPS54355PWP

Voltage Regulators - DC DC Switching Regulators Overview

The TPS54355PWP is a synchronous step-down DC/DC converter from Texas Instruments' SWIFT series. It accepts an input voltage range of 4.5 V to 20 V and provides a fixed positive output of 2.5 V at up to 3 A. The device integrates the controller, power switches, and inductor into a compact HTSSOP (PWP) package with 16 pins. Operating supply current is specified at 9 mA. It functions as a buck regulator designed for efficient power conversion in space-constrained applications.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates synchronous rectification and control logic within a single compact package
• Utilizes SWIFT topology to minimize external component count and board area
• Provides a fixed 2.5 V output suitable for powering digital loads

Voltage Regulators - DC DC Switching Regulators Applications

• Audio equipment power supplies
• Industrial control systems
• Small to medium-sized load powering

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix PWP corresponds to the 16-pin HTSSOP package configuration. Confirm the fixed 2.5 V output requirement matches your system design, as other variants may offer adjustable or different fixed voltages. Ensure thermal management solutions are adequate for the operating environment given the 3 A capability.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.5 V rail is required from a 4.5–20 V source. The integrated inductor simplifies layout compared to discrete solutions. Consider the HTSSOP package size constraints and verify that the 9 mA quiescent current meets efficiency targets for the specific application duty cycle.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the TPS54355 family of SWIFT converters. The PWP suffix specifically denotes the 16-lead High Temperature Shrink Small Outline Package (HTSSOP). It is distinct from other pinouts or output voltages within the broader TPS543xx series.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for TPS54355 variants with different output voltages if 2.5 V is not required. Verify pin compatibility with alternative SWIFT series parts before substitution.
