Texas Instruments UC3865Q is a high-performance offline switching controller designed for full-bridge, half-bridge, and push-pull converter topologies. This 20-PLCC packaged component operates with a switching frequency range of 10kHz to 1MHz, offering flexibility for various power supply designs. Key features include an internal start-up circuit requiring 16.5V for initial operation and a supply voltage range of 10.5V to 22V. The UC3865Q integrates soft-start control for gradual power ramp-up, minimizing inrush current. Its non-isolated output configuration and surface mountable design facilitate integration into compact power solutions. This component is widely utilized in industrial power supplies, consumer electronics, and telecommunications equipment where efficient AC-DC conversion is critical. The 20-PLCC (9x9) package ensures robust thermal performance for demanding applications.
