TPS54872PWP

Special Purpose Regulators Overview

The TPS54872PWP is an 8-A output, 4-V to 6-V input tracking/termination synchronous PWM switcher with integrated FETs. It utilizes the SWIFT topology for high efficiency and compact design. The device features a fixed switching frequency of 350 kHz or 550 kHz, selectable via an external resistor. It operates within a junction temperature range of -40°C to 125°C and is housed in a 28-pin PowerTSSOP package.

Special Purpose Regulators Feature Summary

• Integrated high-side and low-side power FETs for simplified design
• Tracking and termination capabilities for precise voltage sequencing
• SWIFT converter architecture minimizes external component count

Special Purpose Regulators Applications

• Point-of-load regulation for high-density systems
• Voltage sequencing applications requiring tracking
• Telecommunications infrastructure power supplies

Special Purpose Regulators Procurement Notes

Verify the specific suffix (e.g., PWP) against the manufacturer's current datasheet to confirm pinout and thermal specifications. Ensure the selected switching frequency matches the application requirements, as this parameter is determined by external components. Confirm RoHS compliance status through official documentation before procurement.

Special Purpose Regulators Selection Notes

Select this component when an 8-A output current is required from a 4-V to 6-V input source. Consider the SWIFT topology for reduced board space compared to discrete solutions. Evaluate thermal performance based on the 28-PowerTSSOP package limitations under maximum load conditions.

Special Purpose Regulators Part Context

This part belongs to Texas Instruments' SWIFT converter family, designed for high-efficiency step-down conversion. It integrates control logic and power stages into a single IC, distinguishing it from traditional controllers that require external MOSFETs. The series emphasizes compactness and ease of implementation for modern power management needs.
