TPS65632RTET

Overview

The TPS65632RTET is a triple-output power supply IC designed for AMOLED display applications. It integrates three high-efficiency synchronous buck converters to provide VGH, VGL, and AVDD voltages. The device operates with an input voltage range of 2.9V to 4.5V and supports output currents up to 1.2A. It features I2C interface control for programmable parameters and includes protection mechanisms such as over-current and thermal shutdown. Packaged in a 16-pin WQFN (RTER) suitable for -40°C to 85°C operation.

Feature Summary

• Integrates three independent synchronous step-down converters for VGH, VGL, and AVDD generation
• Supports I2C digital interface for precise voltage regulation and status monitoring
• Includes comprehensive protection features including over-current and thermal shutdown
• Optimized for low noise and high efficiency in sensitive AMOLED display panels

Applications

• AMOLED mobile phone display power systems
• Tablet and wearable device display drivers
• High-resolution portable electronic screens

Procurement Notes

Verify the RTER suffix confirms the specific tape-and-reel packaging configuration and temperature grade. Ensure compatibility with existing PCB footprints for the 16-WQFN package. Cross-reference the exact revision level against current design specifications to avoid pinout or functional discrepancies from previous manufacturing batches.

Selection Notes

Select this component when designing power architectures for active-matrix organic light-emitting diode displays requiring integrated VGH, VGL, and analog supply rails. It is suitable for space-constrained portable devices where board area and component count are critical constraints compared to discrete solutions.

Part Context

This part belongs to Texas Instruments' dedicated AMOLED display power management family. It complements other TI display drivers by providing the necessary high-voltage gate drive and analog supplies. The series is engineered to meet the stringent transient response and ripple requirements of modern high-density display technologies.

Replacement Considerations

The TPS65631W serves as a dual-output alternative if only two rails are required. For legacy designs, verify pin-to-pin compatibility with older revisions within the same product line before substitution.
