nodes at the two extreme physical ends of the communication line. Intermediate nodes along the highway must remain unterminated to avoid overloading the driver circuits. PCB Traces and Routing The Highway 09 is a monolithic control IC designed for high-performance switching applications. It integrates a high-voltage power MOSFET alongside complete control circuitry, making it a staple in compact offline power supplies and LED drivers. The Highway 09 IC is available in a 16-pin package, with the following pin configuration: This article provides a deep dive into the technical details, pinout configuration, and application notes based on available datasheet information. What is the HIGHWAY 09 IC? The HIGHWAY09A manages high-frequency resonance switching, user interface control, and structural hardware protection safety loops. Integrated directly into power supply motherboards, its architecture balances processing efficiency with low thermal footprint requirements.
