TPS65651RTET

Overview

The TPS65651RTET is a triple-output power supply integrated circuit designed for AMOLED display applications. It integrates three synchronous step-down converters with input voltage ranges of 4.5 V to 18 V and output currents up to 3 A, 2 A, and 2 A respectively. The device operates within an ambient temperature range of -40°C to +85°C and utilizes a 40-pin RTET package.

Feature Summary

• Integrates three independent synchronous buck converters for flexible power rail generation
• Supports wide input voltage range suitable for battery-powered or external supply systems
• Optimized for driving high-current AMOLED display panels

Applications

• AMOLED display power management
• Mobile device display subsystems
• Portable electronics requiring multi-rail power distribution

Procurement Notes

Verify the specific suffix RTET against official Texas Instruments documentation to confirm pinout and thermal characteristics. Ensure compatibility with PCB layout requirements for the 40-pin package. Cross-reference the datasheet revision date to validate electrical specifications before finalizing procurement.

Selection Notes

Select this component when designing power architectures for AMOLED displays requiring three distinct regulated outputs from a single IC. Consider the 4.5 V to 18 V input range and current capabilities relative to the target display panel's power consumption profile.

Part Context

This part belongs to the TPS65651 series of specialized PMICs focused on display driver power solutions. It consolidates multiple converter functions into a compact form factor, reducing component count compared to discrete designs.

Replacement Considerations

Consult the TI TPS65651 datasheet for officially listed alternative part numbers within the same family that may offer minor functional variations.
