The UCC2813N-2 is an integrated circuit (IC) component that is widely used in switch mode power supplies (SMPS). It belongs to the UCCx813 family of products, which are renowned for their high-performance features and versatility. The UCC2813N-2 is specifically designed to offer enhanced protection features and high efficiency, making it an ideal choice for demanding power supply applications. Let's take a closer look at its key features.
One of the standout features of the UCC2813N-2 is its overvoltage protection capability. It incorporates a feedback network that constantly monitors the output voltage. In case of an overvoltage condition, the IC promptly responds by limiting the output voltage, ensuring the connected load is protected. Additionally, this IC includes an undervoltage lockout (UVLO) feature, which prevents the power supply from operating if the input voltage falls below a certain threshold. This further enhances system protection from potential damage.
Moreover, the UCC2813N-2 offers a flexible soft-start feature. This feature allows the power supply to start up gradually, reducing the inrush current and ensuring a stable power-up sequence. The soft-start time can be easily adjusted using an external timing capacitor, providing customization options for different applications.
