Product Overview: UCC2802QDRQ1 - Texas Instruments

The UCC2802QDRQ1 is a high-performance, low-power BiCMOS current-mode pulse width modulator (PWM) controller from Texas Instruments, specifically designed for automotive and industrial applications. This advanced IC is part of Texas Instruments' renowned UCC28C series, which is engineered to offer exceptional power management solutions for a wide range of voltage regulation tasks.

The UCC2802QDRQ1 operates at a supply voltage ranging from 4.5V to 18V, making it versatile for various systems. Its low startup current of less than 0.5 mA and operating current of 2.5 mA contribute to its efficiency, making it an excellent choice for battery-operated and power-conscious designs.

This controller features a fixed-frequency current-mode control scheme, which provides fast response to load changes and inherent line regulation. With a frequency range of 1MHz, this device can be used to design converters with small physical size, reduced output ripple, and minimized electromagnetic interference (EMI).

The UCC2802QDRQ1 includes a range of protective features to ensure reliability and durability in harsh environments. It comes with under-voltage lockout (UVLO), overcurrent protection, and a programmable soft-start function that mitigates inrush current during startup. Additionally, the device is equipped with an error amplifier, a precision reference voltage, and a totem-pole output stage capable of driving a power MOSFET or IGBT directly.

Packaged in a space-saving 8-pin SOIC, the UCC2802QDRQ1 is optimized for compact layouts and can be easily integrated into a variety of power supply designs, including DC-DC converters, off-line converters, and other switch-mode power supplies. It is qualified for automotive applications, complying with the AEC-Q100 standards, which ensures robustness and performance under extreme conditions.

In summary, the UCC2802QDRQ1 from Texas Instruments is a highly integrated, efficient, and reliable PWM controller that offers a comprehensive solution for advanced power management. Its combination of features and protections makes it ideal for demanding automotive and industrial power systems.
