Texas Instruments UCC2801 Low-Power BiCMOS Current-Mode PWM UCC2801DTRG4

The UCC2801DTRG4 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. With a maximum duty cycle of 50% and a reference voltage of 5V, the UCC2801DTRG4 is suitable for applications requiring precise voltage regulation. It also incorporates internal leading-edge blanking for the current sense signal, which improves performance by reducing noise sensitivity. The controller is specified for operation over a temperature range of -40¬8C to 125¬8C, making it versatile for various environmental conditions. The UCC2801DTRG4 is available in an 8-pin SOIC package, facilitating integration into compact designs.
