TPS650240RHBR

Updated: 2026-09-12

Overview

The TPS650240RHBR is a power management integrated circuit (PMIC) developed by Texas Instruments. It integrates multiple voltage regulators and power management functions into a single chip, simplifying power supply design for portable and embedded systems. The device is housed in a compact VQFN package, making it suitable for space-constrained applications. As a PMIC, the TPS650240RHBR is designed to efficiently manage power distribution in electronic systems. It typically includes features such as buck converters, LDO regulators, and power sequencing capabilities. These features make it particularly valuable in battery-powered devices where power efficiency is critical.

Structure and Working Principle

The TPS650240RHBR combines several power conversion circuits in one package. It typically includes DC-DC buck converters for step-down voltage conversion and low-dropout (LDO) linear regulators for clean voltage outputs. The device operates by converting the input voltage to the required output levels with high efficiency. Internal control circuits manage the power sequencing and voltage regulation processes. The PMIC uses pulse-width modulation (PWM) for the switching regulators to maintain stable output voltages even with varying input voltages or load conditions. This architecture helps minimize power losses while providing reliable power to different system components.

Key Features

The TPS650240RHBR offers several notable features that make it attractive for power management applications. These include high efficiency conversion, typically above 90% for the switching regulators, which extends battery life in portable devices. The integrated design reduces component count and board space requirements. Other important features include programmable power sequencing, which ensures proper startup and shutdown of system voltages. The device often incorporates protection features such as thermal shutdown, overcurrent protection, and undervoltage lockout. These safeguards help prevent damage to both the PMIC and the system it powers.

Application Areas

The TPS650240RHBR finds application in various electronic systems requiring efficient power management. Common applications include portable medical devices, handheld test equipment, and industrial controllers. Its compact size and power efficiency make it particularly suitable for space-constrained designs. In consumer electronics, the PMIC is often used in smartphones, tablets, and digital cameras. The device's ability to manage multiple voltage rails makes it valuable in embedded systems and IoT devices, where different components may require different supply voltages. Its robust design also suits automotive and industrial applications that demand reliable operation in challenging environments.

Maintenance and Precautions

Proper handling and installation are crucial for optimal performance of the TPS650240RHBR. The device should be stored in moisture-sensitive packaging until use and handled with proper ESD precautions. During PCB layout, attention should be paid to thermal management and proper grounding. For long-term reliability, the PMIC should not be operated beyond its specified temperature range or input voltage limits. Designers should ensure adequate heat dissipation, especially when operating at maximum load currents. Following the manufacturer's recommended layout guidelines helps minimize noise and ensure stable operation.

B2B Procurement Guide

When procuring the TPS650240RHBR in bulk, buyers should consider several factors. Lead times can vary depending on market demand, so planning ahead is advisable. Purchasing through authorized distributors ensures genuine components and access to technical support. For high-volume applications, direct engagement with the manufacturer may provide cost advantages. Buyers should verify the required package type and temperature grade for their specific application. Sample quantities are often available for design verification before committing to large orders.
