TPS65262-1RHBR

Overview

The TPS65262-1RHBR is a Texas Instruments PMIC featuring three synchronous buck converters and two low-dropout regulators. It accepts an input voltage range of 4.5V to 18V. The first buck output provides up to 3A with adjustable voltage down to 0.6V. The second and third buck outputs each deliver 1A, also adjustable to 0.6V. The device operates at a fixed switching frequency of 600kHz. It is housed in a 32-VQFN package measuring 5x5 mm.

Feature Summary

• Integrates three synchronous step-down converters and two linear regulators within a single compact package.
• Supports wide input voltage ranges suitable for various power supply architectures.
• Features adjustable output voltages starting from 0.6V for flexible rail generation.

Applications

• Portable electronic devices requiring multiple regulated power rails
• Industrial control systems needing efficient DC-DC conversion
• Communication equipment utilizing synchronized switching frequencies

Procurement Notes

Verify the specific suffix RHBR indicates tape and reel packaging when ordering. Confirm that the -1 variant matches the required current ratings for your design. Ensure compatibility with the 32-VQFN footprint during PCB layout. Check RoHS compliance status if environmental regulations apply to your project requirements.

Selection Notes

Choose this component when five distinct output rails are necessary from a single source. The integrated topology reduces board space compared to discrete solutions. Consider the 600kHz frequency for balancing efficiency and passive component size. Validate thermal performance given the high current capability of the primary buck converter.

Part Context

This part belongs to the TPS65262 family of power management ICs designed for multi-rail applications. It consolidates power regulation functions typically handled by separate components. The device simplifies system design by providing both switching and linear regulation capabilities in one unit.

Replacement Considerations

The TPS65262RHBR serves as a standard alternative within the same series. Verify pinout compatibility and electrical specifications before substitution. Other variants in the TPS6526x family may offer different current ratings or package options.
