The Texas Instruments UCC1804J is a low-power BiCMOS current-mode Pulse Width Modulation (PWM) controller. It is designed for applications requiring efficient power management.
Key electrical specifications include support for Boost, Flyback, and Forward topologies, with a current control mode. The device features a fixed frequency operation and includes an error amplifier, leading-edge blanking, and soft start functionality. The maximum duty cycle is rated at 50%. It operates with a typical starting supply current of 100µA and an operating supply current of 500µA, with an operating frequency up to 1MHz.
The output stage provides a 1A totem-pole drive, and the response time from current-sense to gate drive output is typically 70ns. The voltage reference tolerance is 1.5%.
This component is available in a CDIP (JG) 8-pin package with an area of 64.032 mm². It is important to note that the UCC1804 is not recommended for new designs, and alternative products should be considered for new projects.
