The MCP1633 SEPIC LED Driver Demo Board is a step-up/step-down, switch-mode, DC/DC converter used for LED driver applications. The demo board provides a 200mA constant current source. Other output currents can be obtained with minor modifications to the board’s Bill of Materials (BOM). MCP1633 LED Driver Demo Board utilizes Microchip's MCP1633 high-speed Pulse-Width Modulator (PWM). The...
