UC3843BD1R2G
by onsemi(安森美)The UC3843BD1R2G from onsemi is a current-mode PWM controller used in switching power supplies. It provides the control function around which the power stage, current sensing and feedback circuitry are built. This record covers the surface-mount SOIC-8 version, with eight symbol pins and eight footprint pads. The free KiCad download includes the symbol, the SOIC-8_L5.0-W4.0-P1.27-LS6.0-BL footprint and a 3D model for reviewing component placement in the assembled board. The files come from a real ProtoFlow import that was converted and checked in the editor. Open the part directly in ProtoFlow to use it in a design.
