MCP1630DM-LED2

The MCP1630DM-LED2 is a MCP1630 boost mode LED driver demo board, which is a step up, switch mode, dc to dc converter used for power LED applications. The demo board provides a 350mA or 700mA constant current source with a jumper selection. Other output currents can be obtained with minor modifications to the board. The MCP1630 boost mode LED driver demo board utilises MCP1630V high speed pulse width modulator. The 8 pin MCP1630V device contains the analog components necessary for an analog switch mode control loop including an error amplifier, PWM comparator, and a high current driver pin. The switching frequency and maximum duty cycle for the MCP1630V are determined by an external clock source. An 8 pin PIC12F683 microcontroller is used to provide a 500KHz switching clock for the MCP1630. In addition, the PIC12F683 firmware supervises the circuit output voltage and can optionally dim the LEDs when a potentiometer is attached.
