UCC2808AQDR-1Q1

The UCC2808AQDR-1Q1 from Texas Instruments is a push-pull current mode PWM controller designed for efficient power supply applications. Operating within an input voltage range of 8.3V to 15V, this controller features a maximum operating frequency of 1MHz and a duty cycle of 49%. It is suitable for both off-line and DC-to-DC power supply designs, requiring minimal external components.

The device is housed in a compact 8-SOIC package, making it ideal for space-constrained applications. The surface mountable design simplifies integration into various electronic circuits. Its operating temperature range is from -55°C to 150°C, ensuring reliable performance in demanding environments. The controller utilizes a push-pull topology and offers frequency control features.

Key specifications include a 1MHz operating frequency and a 49% maximum duty cycle. The controller is designed for isolated power supplies. The internal switch is not present, indicating it requires external switching elements. The operating temperature range is broad, from -55°C to 150°C, suitable for industrial and automotive applications.

This component is qualified for automotive applications and offers features like internal soft start and an on-chip error amplifier. The dual output drive stages are arranged in a push-pull configuration, with dead time typically between 60ns to 200ns, limiting each output stage duty cycle to less than 50%.
