The UCC2813PWTR-3G4 is an integrated circuit (IC) component designed by Texas Instruments. This device belongs to the UCC28x3x family of high-speed, low-power, BiCMOS current-mode PWM controllers. It provides robust circuit protections and high-performance PWM regulation for switch-mode power supplies (SMPS).
One of the key features of the UCC2813PWTR-3G4 is its ability to operate in both voltage mode and current mode control schemes, making it suitable for a wide range of applications. It offers precise regulation and quick transient response, ensuring stable and reliable power supply performance.
The IC incorporates advanced circuitry that enables various protection features, ensuring the safety and prolonging the lifespan of the power supply. These include input undervoltage lockout (UVLO), cycle-by-cycle current limiting, leading-edge blanking (LEB), and overvoltage protection (OVP). These protections guard sensitive components against overcurrent, overvoltage, and other potential faults.
Furthermore, the UCC2813PWTR-3G4 includes a totem pole output stage able to source and sink high-current pulses, allowing efficient drive of both power MOSFETs and IGBTs. Multiple adjustable parameters, such as the switching frequency, can be programmed externally using passive components to suit specific application requirements.
The IC also features a dedicated "Error Amplifier" pin, providing flexibility in selecting the control loop compensation components
