Texas Instruments UC3875QP is a highly integrated, high-frequency switch-mode power supply controller designed for offline, full-bridge topologies. This 28-PLCC package component operates at a switching frequency of up to 1MHz, enabling compact and efficient power conversion. Key control features include frequency control, soft-start, and synchronization capabilities, allowing for precise management of power stages. The UC3875QP incorporates current limiting for fault protection and supports a 100% duty cycle. It requires a supply voltage between 9.5V and 20V, with a start-up voltage of 10.75V. This device is suitable for applications requiring non-isolated output and is commonly found in industrial power supplies and lighting control systems. The 28-PLCC (11.51x11.51) package is designed for surface mounting.
