TPS65262-2RHBT

Overview

The TPS65262-2RHBT is a Power Management IC featuring three synchronous buck converters and two low-dropout regulators. It accepts an input voltage range of 4.5V to 18V. The buck outputs provide adjustable voltages down to 0.6V with maximum currents of 3A, 1A, and 1A respectively. The LDOs deliver 350mA and 150mA. The device operates at a fixed switching frequency of 600kHz and supports temperatures from -40°C to 85°C in a 32-VQFN package.

Feature Summary

• Integrates three high-current synchronous step-down converters for efficient power distribution
• Includes dual low-dropout linear regulators for noise-sensitive analog loads
• Supports wide input voltage ranges suitable for battery-powered systems

Applications

• Portable electronic devices requiring multi-rail power management
• Industrial control systems with mixed digital and analog loads
• Communication equipment needing stable voltage regulation

Procurement Notes

Verify the complete part number including the suffix to ensure correct packaging and temperature grade. Confirm that the specific revision matches the design requirements. Check for any recent product change notices regarding material or assembly site updates before finalizing procurement orders.

Selection Notes

Select this component when a single solution is needed for multiple voltage rails. Ensure the total current demand does not exceed the specified limits for each regulator. Consider thermal performance in the final enclosure design due to the integrated nature of the converters.

Part Context

This part belongs to the TPS65262 family of PMICs designed for space-constrained applications. It consolidates multiple power stages into one compact footprint, reducing board area compared to discrete solutions. The RHBR/RHBT suffixes indicate different tape and reel configurations.

Replacement Considerations

Direct substitutes include TPS65262RHBR which shares identical electrical specifications but differs in packaging format. Other variants within the TPS6526x series may offer similar functionality but require verification of pin compatibility and output current ratings.
