The UC3874DWTR-1 is a synchronous step-down (Buck) controller designed for high efficiency power conversion in battery-powered applications. It supports an input voltage range of 4.5V to 36V and can achieve switching frequencies up to 300kHz.
This controller utilizes average current mode control for tight output voltage regulation and superior transient response. It features a programmable standby mode to improve light load efficiency by reducing quiescent current. The device drives external N-channel MOSFETs for optimal efficiency and offers complementary 1 Amp outputs with regulated gate drive voltage.
Designed for applications demanding high performance and long battery life, such as laptop computers, consumer products, communications systems, and aerospace. The UC3874DWTR-1 is available in a surface-mount 18-SOIC package, suitable for various electronic designs.
Key electrical characteristics include a maximum duty cycle of 100%, a single output phase, and soft start control features. The operating temperature range is 0°C to 70°C (TA).
