Page 15: Chapter 2. Installation And Operation
ABOUT THE MCP19117 FLYBACK STAND-ALONE EVALUATION BOARD The MCP19117 is a digitally-enhanced, power analog, synchronous low-side PWM controller. The GUI was developed to assist users in easily configuring the MCP19117 and evaluating it in their target application. The MCP19117 Flyback Stand-Alone Evaluation Board is designed to operate from a single supply (nominal 8V to 14V, 24V maximum). -
