UCC38083PWG4

The UCC38083PWG4 is an integrated circuit (IC) component designed by Texas Instruments, which belongs to the UCC38xx family of high-performance current mode controllers. It is widely used in switch-mode power supplies (SMPS) and other applications that require a well-regulated power conversion. Key Features of UCC38083PWG4: 1. Current Mode PWM Controller: The UCC38083PWG4 operates as a current mode PWM controller, providing a precise and stable control of the output voltage in SMPS applications. It uses a voltage feedback loop to regulate the output and maintain excellent line and load regulation. 2. Enhanced PWM Controller: This IC utilizes various techniques to enhance its performance. It employs an externally programmable soft-start feature for a controlled startup of the power supply, preventing excessive inrush current. It also features adjustable frequencies (up to 1 MHz) and a maximum duty cycle of 100% for versatile power supply designs. 3. Comprehensive Protection Features: The UCC38083PWG4 embeds multiple protection features to ensure the safety and reliability of the power supply system. It includes overvoltage protection (OVP), undervoltage lockout (UVLO), thermal shutdown, cycle-by-cycle current limiting, and a shutdown pin for controlled power shut off
