TechnologyDK1203 with Switching Controllers DIP-8 RoHS is a 8-pin dual in-line package (DIP) integrated circuit (IC) manufactured by DongKe Technology. It is a switching controller IC, with logic levels operating from -40 to +85 °C. In addition, the DK1203 is compatible with RoHS (Restriction of Hazardous Substances) specifications – it is built using hazardous materials-free components. The DK1203 offers high reliability and stability, and can be used for wide range of PWM/PFM switching power supplies. It provides a full set of protections like short circuit protection, thermal overload protection, over voltage protection, and over current protection. Furthermore, the DK1203 has a built-in under voltage lockout (UVLO) circuit, which allows the unit to automatically power up once a power source is connected.
