Regulated output voltage selection
1. The regulated output voltage can be selected to be either 3.3V or 5.0V. The
2. If a shorting jumper is not present, the regulated output voltage will default to
3. The output voltage selection input is read by the PIC10F200 at power-up only.
Output voltage present indication
The MCP1630 1A Bias Supply Demo Board has a LED to indicate the presence of
output voltage. The LED will be illuminated when the output voltage is present.
Programming
Header J4 is provided for in-system circuit programming.
regulated output voltage is selected by placing a shorting jumper on the Output
Voltage Selection Header (J3). By shorting pins 1 and 2, the regulated output
voltage will be 3.3V. By shorting pins 2 and 3, the regulated output voltage will be
5.0V.
5.0V.
Therefore, the output voltage cannot be changed dynamically without
modification of the factory-installed firmware. Input power must be removed or
cycled in order for a change to take effect.
