TPS65150RGER

Updated: 2026-09-25

Overview

The TPS65150RGER is a specialized power management integrated circuit developed by Texas Instruments for LCD display applications. This device efficiently generates the multiple voltage rails required by modern TFT-LCD panels, including positive and negative voltage supplies. Its compact QFN-24 package makes it suitable for space-constrained designs commonly found in portable electronics. The IC integrates several power conversion circuits into a single chip, reducing component count and board space requirements. It's particularly valued in applications where power efficiency and noise performance are critical, such as medical displays and industrial control panels.

Structure and Working Principle

The TPS65150RGER combines a step-up converter, inverting charge pump, and linear regulators in one package. The step-up converter generates the main positive supply voltage (typically +15V) from a lower input voltage (2.7V to 5.5V). A charge pump creates the negative supply rail (-15V), while integrated LDOs provide additional regulated voltages. The device employs pulse-width modulation (PWM) for efficient power conversion and includes feedback loops to maintain stable output voltages despite load variations. An internal oscillator controls the switching frequency, which can be synchronized to an external clock to minimize interference in sensitive applications.

Key Features

The TPS65150RGER stands out for its high efficiency (typically 85-90%), which helps extend battery life in portable devices. The integrated solution provides up to four output voltages (+15V, -15V, +5V, and +3.3V) from a single input, significantly simplifying power supply design. Other notable features include soft-start functionality to prevent inrush current, thermal shutdown protection, and a wide operating temperature range (-40°C to +85°C). The device's low output noise (typically <50mVpp) makes it suitable for high-quality display applications where clean power is essential for optimal image quality.

Application Areas

The TPS65150RGER finds primary use in LCD display systems across various industries. Consumer electronics applications include tablets, e-readers, and portable media players where compact power solutions are mandatory. Industrial applications encompass human-machine interfaces (HMIs), medical displays, and test equipment. Automotive infotainment systems and aviation displays also benefit from this IC's reliability and temperature performance. Its ability to operate from low input voltages makes it particularly suitable for battery-powered devices, while the robust design meets the requirements of harsh operating environments.

Maintenance and Precautions

Proper PCB layout is crucial when implementing the TPS65150RGER. Follow manufacturer guidelines for component placement, especially for the switching converter's inductor and capacitors. Ensure adequate thermal vias under the package's exposed pad for heat dissipation. ESD precautions should be observed during handling and installation. Input and output capacitors should be low-ESR types specified in the datasheet. Avoid operating near maximum ratings for extended periods, and monitor junction temperature in high-ambient environments to maintain long-term reliability.

B2B Procurement Guide

When sourcing the TPS65150RGER, verify the manufacturer's part number and package marking to ensure authenticity. Consider purchasing directly from authorized distributors or the manufacturer to avoid counterfeit components. Volume pricing typically becomes competitive at order quantities above 1,000 units. Evaluate alternative solutions for non-critical applications where cost is a primary concern. For new designs, request evaluation boards and reference designs from the manufacturer to accelerate development. Lead times may vary based on market demand, so plan procurement accordingly for production schedules.
