UCC28C44DR
by TI(德州仪器)UCC28C44DR from Texas Instruments is a current-mode PWM controller for switch-mode power-supply designs. It provides the control function around which the switching stage, sensing circuitry, and feedback network are built. The supplied board representation is surface mount, using an SOIC-8 footprint with eight pads matched by an eight-pin schematic symbol. For KiCad, the free download brings together that symbol, footprint SOIC-8_L4.9-W3.9-P1.27-LS6.0-BL, and a 3D model that supports board assembly review. The source was a real ProtoFlow import; its conversion was checked in the editor. Open UCC28C44DR directly in ProtoFlow when developing the controller circuit and PCB layout.
