TPS54314PWP

Voltage Regulators - DC DC Switching Regulators Overview

The TPS54314PWP is a synchronous buck PWM DC/DC converter from Texas Instruments, part of the SWIFT family. It operates with an input voltage range of 3 V to 6 V and provides a fixed output voltage of 1.8 V at up to 3 A. The device features a switching frequency of 700 kHz and utilizes a 20-PowerTSSOP package. It includes integrated power MOSFETs and supports operation temperatures from -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates high-side and low-side power MOSFETs for efficient step-down conversion
• Utilizes SWIFT topology to minimize external component count and solution size
• Provides fixed 1.8 V output voltage regulation

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for embedded systems
• Power supply stages for portable battery-operated devices
• Industrial control system voltage regulation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'PWP' corresponds to the 20-PowerTSSOP package and tape-and-reel or cut-tape availability as required. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to assembly planning. Ensure the fixed 1.8 V output matches the target design requirements, as this variant does not support adjustable output voltages.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.8 V output is required within a 3 V to 6 V input range. The 700 kHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. The 3 A current capability suits moderate load applications. Consider the 20-PowerTSSOP package for thermal performance and board space constraints in compact designs.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the TPS5431x series of low-input voltage synchronous buck converters. It shares architectural similarities with the TPS54313 and TPS54315 but differs in fixed output voltage settings. The SWIFT family emphasizes simplified design through integrated magnetic components and minimal external circuitry requirements.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The TPS54314PWPR serves as the reel-pack equivalent. For adjustable output variants, consider the TPS54315. Note that the TPS54313 offers a 1.5 V fixed output but may have different switching frequency options.
