Product Overview: Texas Instruments UCC2808AN-2

The Texas Instruments UCC2808AN-2 is a low-power, BiCMOS current-mode pulse-width modulation (PWM) controller designed for a wide range of power supply applications. This integrated circuit (IC) is tailored to offer precise control in switch-mode power supplies, DC-DC converters, and other power conversion devices. Its compact design and advanced features make it an ideal choice for engineers looking to enhance the efficiency, reliability, and performance of their power management systems.

Key Features

• Low Startup and Operating Current: The UCC2808AN-2 is optimized for low-power operations, featuring a startup current of typically 0.5µA and an operating current of typically 3.6mA, which contributes to the overall efficiency of the power system.
• High-Frequency Operation: With the capability to operate at frequencies up to 1MHz, this controller supports the use of smaller, less expensive passive components, resulting in a more compact and cost-effective power supply design.
• Current Mode Control: The current mode control provides inherent line feed-forward, cycle-by-cycle current limiting, and ease of loop compensation, which altogether enhance the performance under varying load conditions.
• Trimmed Oscillator Discharge Current: This feature helps to achieve a consistent and precise dead time over the entire temperature range, which is critical for optimizing system efficiency and performance.
