TPS65262-1RHBT

Overview

The TPS65262-1RHBT is a Texas Instruments PMIC featuring three synchronous buck converters and two LDOs. It operates from a 4.5V to 18V input supply. Output 1 provides up to 3A, while outputs 2 and 3 deliver 1A each. All outputs are adjustable down to 0.6V. The device integrates a fixed 600kHz switching frequency for the buck regulators. It is housed in a 32-VQFN (5x5) package with an exposed pad for thermal management.

Feature Summary

• Integrates three high-current synchronous buck converters and two low-dropout linear regulators within a single compact package.
• Supports wide input voltage ranges suitable for various system power rails.
• Features adjustable output voltages starting from 0.6V for flexible core and peripheral power requirements.

Applications

• Portable electronic devices requiring multiple regulated power rails
• Industrial control systems needing robust power management
• Automotive infotainment and instrumentation modules

Procurement Notes

Verify the specific suffix RHBT against your design requirements, as it denotes the tape-and-reel packaging variant. Confirm that the 32-VQFN footprint matches your PCB layout constraints. Ensure compatibility with the 4.5V to 18V input range for your application's power source. Check for any recent Product Change Notifications regarding assembly sites or materials before finalizing procurement.

Selection Notes

Choose this component when a combination of high-current buck regulation and precise LDO performance is required in a small form factor. The integrated nature reduces external component count compared to discrete solutions. Consider the 600kHz fixed frequency for EMI planning. Verify that the thermal dissipation capabilities of the 32-VQFN package meet the thermal budget of your enclosure design under maximum load conditions.

Part Context

This part belongs to the TPS65262 family of power management ICs designed for complex multi-rail applications. It consolidates power conversion functions typically handled by separate regulators. The -1 variant often indicates specific internal configuration or pinout variations within the series. It serves as a central power distribution unit for microprocessors and memory subsystems.

Replacement Considerations

TPS65262RHBR is a functional equivalent with identical electrical specifications but differs in packaging format. TPS65262RHBT is the same device without the -1 suffix distinction in some contexts, though verification of the specific datasheet revision is recommended. Cross-reference with TPS65261 if LDO outputs are not required.
