Detailed Specifications and Markings

The TPS51225C is housed in a compact, 20-pin QFN package, making it suitable for space-constrained applications on printed circuit boards (PCBs). You can identify this specific part by its markings, which include TPS51225C, TPS 51225C, and the full manufacturer part number TPS51225CRUKR. These identifiers ensure you are purchasing the correct component for your needs. We provide authentic, brand new chips that meet the original Texas Instruments specifications, ensuring optimal performance and reliability for your power management system designs.

Important Version Compatibility Information

Please be aware that the TPS51225C is not a direct replacement for the TPS51225B. A key functional difference is that the VREG3 and VREG5 regulators are 'always on' in the TPS51225C version. This is a critical distinction that affects the power-on sequence and overall behavior of the circuit it is integrated into. We urge you to verify your schematic and system requirements to confirm that the 'C' version is the correct part for your application before you decide to purchase this item.

Professional Installation Required

This is a surface-mount device (SMD) that demands specialized skills and equipment for successful installation. To replace this type of chip, you must have access to and be proficient with a hot-air soldering station and a pre-heating station. These tools are necessary to safely remove the old component and solder the new one without damaging the chip or the motherboard. We recommend that only experienced technicians or electronics hobbyists with the proper setup attempt this repair. This product is for sale to qualified individuals.

Essential Handling and Preparation

Like many advanced integrated circuits, the TPS51225C is sensitive to Electrostatic Discharge (ESD). It is crucial to follow proper ESD-safe handling procedures at all times to prevent permanent damage to the component. Furthermore, to ensure a successful reflow soldering process, you must prebake this chip at 125 degrees Celsius for a full 24 hours. This process safely removes any absorbed moisture, which could otherwise cause the chip to crack or delaminate when exposed to high soldering temperatures, a phenomenon known as the 'popcorn effect'.

Authentic Product and Packaging

We believe in transparency, which is why the images shown on this page are of the actual item you will receive. You can order with confidence, knowing what to expect. The chips are brand new and will be delivered in a protective reel package, which is standard for ensuring the integrity of electronic components during transit and storage. Each purchase includes a quantity of two pieces of the TPS51225C controller, providing excellent value whether you need a spare or are working on multiple devices.

Common Applications and Use Cases

The TPS51225C dual synchronous buck controller is commonly found in laptop motherboards, graphics cards, and other portable or embedded systems where efficient power regulation is paramount. It is an essential part for technicians performing component-level board repairs, enabling them to restore functionality to devices with power-related issues. By integrating this controller, you can create stable and reliable step-down voltage rails necessary for powering CPUs, GPUs, and other critical subsystems, ensuring long-term operational stability and performance for the device.
