UCC28C43DR General Description
The UCC28C43DR is a high-performance current-mode PWM controller designed for low standby power applications. It operates at a fixed frequency and is capable of supporting both isolated and non-isolated power supply designs. The device features an internal 700V startup switch, enabling it to work with a wide range of input voltages.Key features of the UCC28C43DR include cycle-by-cycle peak current limiting, line voltage feedforward compensation, soft-start control, and adjustable precision internal reference. Additionally, it offers protection features such as overvoltage protection, undervoltage lockout, and thermal shutdown.The UCC28C43DR is available in a small SOIC-8 package, making it suitable for compact designs with limited board space. It is commonly used in applications such as auxiliary power supplies, LED drivers, and standby power supplies for appliances and consumer electronics.
