TPS54120RGYR

Overview

The TPS54120RGYR is a dual-output power management integrated circuit from Texas Instruments, combining one synchronous buck converter and one low-dropout linear regulator. It operates with an input voltage range of 2.2 V to 17 V. The buck channel provides an adjustable output voltage between 0.8 V and 6 V with a maximum current of 1 A. The LDO channel offers a similar adjustable range of 0.8 V to 6 V at 1 A. The device features an adjustable switching frequency from 200 kHz to 1.2 MHz and is housed in a 24-VQFN package measuring 5.5 mm by 3.5 mm.

Feature Summary

• Integrates a synchronous step-down converter and a linear regulator for combined power delivery
• Features adjustable switching frequency ranging from 200 kHz to 1.2 MHz
• Includes internal soft-start and sequencing control for the two outputs

Applications

• Power systems for Xilinx FPGAs and CPLDs
• Portable equipment requiring multiple voltage rails
• Battery-powered devices with mixed analog and digital loads

Procurement Notes

Verify the specific suffix RGYR corresponds to the 24-VQFN (5.5x3.5) package and tape-and-reel packaging configuration. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure the ordering quantity aligns with the manufacturer's standard reel sizes to avoid cut-tape premiums or availability issues during procurement.

Selection Notes

Select this component when a single IC solution is needed to provide both high-efficiency switching regulation and low-noise linear regulation. It is suitable for designs where space is constrained due to its compact 24-VQFN footprint. Consider the adjustable frequency range if electromagnetic interference filtering needs to be optimized for specific application frequencies.

Part Context

This part belongs to the TPS54120 family, which is designed specifically for applications requiring simultaneous buck and LDO regulation. It serves as a consolidated power management solution, reducing the bill of materials compared to using separate discrete regulators. The device is commonly utilized in embedded systems and communication modules.
