GETTING STARTED
The MCP1630 Coupled Inductor Boost Converter Demo Board is fully assembled and
tested. The board requires the use of an external input voltage source (3.0V to 5.5V)
and external load of Max 1W.

return side (-) of input source to TP2. Refer to Figure 2-1. The input voltage
source should be limited from 3.0V to 5.5V range. As the input voltage is applied
and the system powers up, the firmware program of the PIC12F683 device will
initialize and help the converter remain in low-power sleep mode (<0.1 µA) until
the S1 push button is pressed for > 2 seconds by the user. If the S1 push button
is pressed for less than 2 seconds, the converter will not power up.
Inductor Boost Converter Demo Board is powered on delivering an output
voltage of 40V with a maximum power of 1W. The S1 push button can also be
used to provide a variable output voltage from 40V to 15V in 5V steps. Each
depression of the S1 push button for <2 seconds (short key press) after the
converter is enabled will provide a decrementing output voltage from 40V to 15V
range in reducing 5V steps in cyclic order.
