The TPS54427DDAR is an integrated circuit (IC) component designed for DC/DC buck conversion applications. It is specifically developed for applications that require a high-efficiency and compact power solution. This IC offers several key features that make it stand out in the market.
One of the prominent features of the TPS54427DDAR is its wide input voltage range. It can handle an input voltage range from 4.5V to 18V, making it suitable for a variety of power supply applications, including industrial, telecom, and consumer electronics.
Another important feature is its high output current capability. The TPS54427DDAR can deliver a continuous output current of up to 4A, along with a peak current limit of 6A. This allows it to power devices with high power demands efficiently.
The TPS54427DDAR also incorporates an adaptive on-time control architecture that enables fast transient response and maintains a stable output voltage during sudden load variations. This makes it ideal for applications that require a responsive power supply, such as microprocessors and field-programmable gate arrays (FPGAs).
Furthermore, this IC comes with a built-in voltage reference and features an adjustable soft-start time, which allows for controlled start-up and reduced inrush current. It also offers protection features like thermal shutdown, overcurrent protection, and undervoltage lockout, ensuring the safety and reliability of the system
