UCC2804DTR Description

Short technical summary and product information.

The UCC2804DTR from Texas Instruments is a high-speed, low-power integrated circuit that functions as a current-mode PWM controller. It is suitable for off-line and DC-to-DC fixed frequency switching mode power supplies. This controller supports multiple topologies including Boost, Flyback, and Forward configurations.

 

Key electrical specifications include an operating voltage range of 8.3V to 12V, with UVLO (Under-Voltage Lockout) at 12.5V and 8.3V. It can operate at switching frequencies up to 1MHz, with a maximum duty cycle of 49%. The device features current limiting for fault protection and offers frequency control.

 

Packaged in an 8-SOIC (0.154", 3.90mm Width) surface-mount package, the UCC2804DTR operates within a temperature range of -40°C to 85°C (TA). It boasts a typical starting supply current of 100µA and an operating supply current of 500µA. Additional features include internal soft start and leading-edge blanking, with a typical response time from current-sense to gate drive output of 70ns. The voltage reference has a tolerance of 1.5%.
