The UCC3804DTR is a low-power BiCMOS current-mode PWM controller designed for use in switching mode power supplies and DC-to-DC converters. It features a typical starting supply current of 100OºA and an operating supply current of 500OºA, allowing for efficient power management. The device operates at frequencies up to 1MHz and includes internal soft start and fault soft start capabilities, enhancing system reliability. The UCC3804DTR provides a 1A totem-pole output with a typical response time of 70ns from current sense to gate drive output. It has a voltage reference tolerance of 1.5%, ensuring stable operation. The device is specified for a temperature range of -40¬8C to 125¬8C, making it suitable for various applications, including automotive power supplies and battery-operated systems. The UCC3804DTR is available in an 8-pin SOIC package, compatible with the UC3842 and UC3842A pinout, facilitating easy integration into existing designs.
