The UCC3801 is a low-power BiCMOS current-mode PWM controller designed for use in switch 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 during startup conditions. The UCC3801 provides internal leading-edge blanking of the current sense signal, which improves performance by reducing noise sensitivity. It has a totem-pole output capable of driving up to 1A, with a typical response time of 70ns from current sense to gate drive output. The voltage reference tolerance is specified at 1.5%, ensuring stable operation across varying conditions. This controller is suitable for applications in automotive power supply units and battery-operated systems, and it operates within a temperature range of -40°C to 125°C. The UCC3801 is available in an 8-pin SOIC package, making it a compact solution for various power management needs.
