Important Note: TPS51225C vs. TPS51225B

Please be aware that the TPS51225C is not a direct replacement for the TPS51225B. A key difference lies in the operation of the VREG3 and VREG5 linear regulators; on the TPS51225C, both VREG3 and VREG5 are "always on". This distinction is crucial for correct circuit functionality and system integration. Verify your specific design requirements to ensure compatibility before purchasing. Understanding this variation, including markings like TPS51225CRUKR or TPS 51225C, will prevent potential issues and ensure seamless performance of your electronic assemblies.

Essential Skills for Installation

Replacing or installing integrated circuits like the TPS51225C requires specialized knowledge and equipment. This task is recommended only for individuals possessing the necessary skills in surface-mount device (SMD) rework. A hot-air soldering station and a pre-heating station are essential tools for successful installation and to prevent damage to the component or the printed circuit board. Attempting this without the proper expertise and tools can lead to component failure or circuit damage when working with QFN20 packages.

Handling ESD Sensitive Devices

The TPS51225C is an Electrostatic Discharge (ESD) sensitive device. Proper ESD handling practices are mandatory to prevent damage to the chip. This includes using grounded wrist straps, ESD-safe mats, and appropriate tools when handling the component. Failure to observe these precautions can lead to latent or catastrophic failure of the IC, rendering it unusable. Always work in an ESD-protected area to maintain the integrity and reliability of these sensitive electronic components, especially the TPS51225CRUKR variant.

Prebaking for Optimal Performance

To ensure optimal performance and prevent damage during the reflow soldering process, it is highly recommended to prebake the TPS51225C chip. Bake the component at 125 degrees Celsius for a continuous 24-hour period. This process effectively removes any absorbed moisture, which can otherwise cause "popcorning" or delamination when the chip is exposed to high reflow temperatures. Adhering to this prebaking procedure is a critical step for reliable assembly and long-term durability of the dual synchronous buck controller.

Product Condition and Packaging Details

You will receive two brand new TPS51225C dual synchronous buck controller chips. These components are supplied in a reel package, ensuring they are protected and easy to handle for automated or manual assembly processes. The reel packaging also helps maintain the integrity of the leads and the body of the ICs until they are ready for use. Rest assured, these are genuine, factory-fresh parts, identified by markings such as TPS51225C or TPS 51225C, ready for your power management project.

Warranty and Authenticity

These TPS51225C controllers come with a 180-day warranty, providing you with peace of mind and assurance of their quality. The pictures displayed in this listing are of the actual items you will receive, so you can be confident in what you are purchasing. We stand by the authenticity and functionality of our components, ensuring they meet the specifications and performance standards expected from Texas Instruments products like the TPS51225CRUKR.
