UCC28881DR General Description

The UCC28881DR is a pulse width modulation (PWM) controller manufactured by Texas Instruments. This device is specifically designed for controlling resonant half-bridge converters in various power supply applications. The UCC28881DR features a wide input voltage range of 4.5V to 21V, making it suitable for a range of power supply designs. It also includes an internal 700V startup switch and supports both constant voltage (CV) and constant current (CC) modes of operation. This controller offers built-in protection features such as input undervoltage lockout (UVLO), output overvoltage protection, and overcurrent protection. It also includes a frequency jittering function to help reduce electromagnetic interference (EMI) in the system.The UCC28881DR is available in a small SOIC-8 package, making it suitable for space-constrained applications.
