The UCC2808A-2EP from Texas Instruments is a robust, low-power, BiCMOS current-mode pulse-width modulation (PWM) controller designed for a wide range of power supply applications. This advanced controller is specifically engineered to meet the stringent requirements of space-constrained and energy-efficient power systems.

With its dual-output drive stages, the UCC2808A-2EP is capable of directly driving a power MOSFET or IGBT. This feature simplifies the design process and reduces external component count, making it an ideal choice for isolated and non-isolated power supplies. The device operates at a fixed frequency that is programmed by an external resistor, offering precise control over the switching characteristics of the power supply.

One of the key advantages of the UCC2808A-2EP is its ability to operate with a startup current of just 0.5µA and a run current of 2.5mA. This low power consumption is essential for applications that demand high efficiency and minimal standby power loss. The controller also includes an undervoltage lockout feature with hysteresis, ensuring stable operation under varying input voltage conditions.

The UCC2808A-2EP is designed with protection features such as cycle-by-cycle current limiting and thermal shutdown, which safeguard the power supply and the end application against over-current and over-temperature conditions. The controller's soft-start function minimizes stress on the power stage during startup, extending the life of the power supply.

This controller is available in an extended temperature range, making it suitable for industrial and military-grade applications. The UCC2808A-2EP is offered in a variety of packages, including the space-saving 8-pin SOIC, which is ideal for compact power supply designs.

Overall, the UCC2808A-2EP is a versatile, efficient, and reliable solution for designers looking to optimize their power supply designs with a high-performance PWM controller. Its combination of low-power operation, comprehensive protection features, and space-efficient packaging makes it an excellent choice for a broad range of applications, including switching power supplies, DC-DC converters, and power inverters.
