MCP1630 Automotive Input Triple Output Converter Demo Board User’s Guide

2.3 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.

2.3.1 Power Input and Output Connection

2.3.1.1 POWERING THE MCP1630 AUTOMOTIVE INPUT TRIPLE OUTPUT

CONVERTER DEMO BOARD

1. Connect the positive side of the input source (+) to TP2. Connect the negative or

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.

2. Once the SW1 push button is pressed, the MCP1630 Automotive Input Triple

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.

3. Again, a subsequent pressing of the SW1 push button during normal operation

of the MCP1630 Automotive Input Triple Output Converter Demo Board will

power-off the converter.
