GETTING STARTED
The MCP1630 Automotive Input Triple Output Converter Demo Board is fully
assembled and tested for Automotive Input. The board requires the use of an external
input voltage source (+6.5V to 40V) and external load for three outputs.

return side (-) of input source to TP1 Refer to figure 2-1. The input voltage should
be limited from 6.5V to 40V 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 uA) until the SW1 push
button is pressed by the user.
Output Converter Demo Board is powered on delivering the three output volt-
ages of 3.3V at 1.2A (Maximum current), 1.2V at 600 mA (Maximum current) and
4.7V at 150 mA (Maximum current) respectively.
