The UCC3895N is an advanced Phase Shift Switching Controller manufactured by Texas Instruments. It is a BiCMOS integrated circuit which allows for precise control of the switching frequency and phase shift of a wide range of power topologies. It is optimized for high performance to reduce EMI, improve power factor, and provide efficient power conversion. It includes an adaptive programmable loop compensation system, an oscillator, a pair of gate drivers, and fault protection circuitry for over-current and over-voltage. The UCC3895N is suitable for a variety of applications such as power factor correction, ac-dc converters, dc-dc converters, and motor controllers.
