GETTING STARTED
The MCP1631HV Digitally Programmable Current Source Reference Design is fully
assembled and tested for driving and dimming power LEDs. At the output, one or more
LEDs can be connected in parallel or series topology. With the default firmware, the
board can drive a 700 mA load with 9V overvoltage protection. This board requires an
external voltage source within a range of +3.5V to +16V input. User supplied LED’s are
also required to evaluate the reference board. A user supplied thermistor mounted on
the LED package is needed to use the thermal shutdown feature in firmware.
