TPS65631DPDR

Overview

The TPS65631DPDR is a dual-output AMOLED display power supply manufactured by Texas Instruments. It integrates two high-voltage linear regulators capable of sourcing up to 200 mA each, designed for driving OLED pixel and common electrodes. The device operates from a single input voltage range of 2.9 V to 4.5 V. It features an integrated charge pump to generate negative output voltages required for certain display biasing configurations. The component is housed in a 16-pin WQFN package and supports operation across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates dual high-voltage linear regulators for independent pixel and common electrode drive
• Includes internal charge pump circuitry for negative voltage generation
• Supports low-power sleep modes with minimal current consumption during standby

Applications

• Active Matrix Organic Light-Emitting Diode (AMOLED) display panels
• Mobile phone display subsystems
• Portable media player screen drivers

Procurement Notes

Verify the specific suffix DPDR against the manufacturer datasheet to confirm the tape-and-reel packaging configuration and pinout orientation. Ensure the input voltage supply matches the specified 2.9 V to 4.5 V range to prevent regulator malfunction. Confirm thermal management requirements for the WQFN package under maximum load conditions.

Selection Notes

Select this component when a compact solution for dual-rail OLED biasing is required without external discrete regulators. Compare against the TPS65632 if triple-output capability is necessary. Evaluate the fixed output voltage options against the specific forward voltage requirements of the target display panel to ensure adequate headroom for regulation.

Part Context

This part belongs to the TPS65631 family of dedicated display power management ICs. It serves as a specialized driver within Texas Instruments' portfolio for portable electronics, distinct from general-purpose DC-DC converters. The device simplifies board design by consolidating multiple power rails into a single small-footprint package.
