TPS65262RHBR

Overview

The TPS65262RHBR is a Power Management Integrated Circuit (PMIC) from Texas Instruments, housed in a 32-VQFN (5x5 mm) package. It integrates five output regulators: three synchronous buck converters and two low-dropout linear regulators (LDOs). The device operates with an input voltage range of 4.5V to 18V and supports a switching frequency of 600kHz. Output capabilities include adjustable voltages down to 0.6V, with current ratings of 3A for the primary buck, 1A for secondary bucks, and unspecified currents for the LDOs. It functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates three synchronous buck converters and two LDOs for comprehensive power management
• Supports I2C control for dynamic voltage scaling and configuration
• Features compact 32-pin VQFN packaging for space-constrained designs

Applications

• Portable electronic devices requiring multi-rail power sequencing
• Industrial control systems needing robust power regulation
• Communication equipment utilizing I2C-configurable power rails

Procurement Notes

Verify the specific suffix RHBR against the manufacturer's datasheet to confirm pinout and thermal pad specifications. Ensure compatibility with the target PCB footprint and soldering profile. Confirm that the 600kHz switching frequency aligns with electromagnetic interference requirements. Validate input voltage ranges against the system's power source characteristics before integration.

Selection Notes

Select this component when a single IC solution is required to manage multiple voltage rails efficiently. It is suitable for applications demanding both high-efficiency switching regulation and low-noise linear regulation. Consider the 32-VQFN package constraints for thermal dissipation and board layout. Verify that the integrated features meet the specific current and voltage requirements of the target subsystems without external components.

Part Context

The TPS65262 belongs to the TPS6526x family of PMICs designed for portable and industrial applications. It consolidates multiple power stages into a single chip, reducing bill of materials and board space. The RHBR variant denotes the specific tape-and-reel packaging format. This series is engineered to simplify power design by integrating control logic and protection features typically found in discrete solutions.

Replacement Considerations

Consult the official TPS65262 datasheet for confirmed cross-reference part numbers. Verify functional equivalence regarding pinout, electrical parameters, and thermal performance before substitution.
