FIGURE 2-1:
2.2.3
The Dimming Push Button provides the option to adjust the LEDs’ luminous intensity
in eight steps. Connect the Dimming Push Button to the J1 header between GND
(Pin 3) and Pin 4.
2.2.4
Connect a power supply to J2 to power up the MCP1630 Sepic Automotive LED Driver
Reference Design. Ensure that the power supply has the (+) terminal connected to the
J2 terminal block at Pin 1 (left), and the (–) terminal connected to Pin 2 (right). The input
voltage source should be limited to a range from 9V to 16V. Ensure that the chosen
power supply can provide enough current at the selected voltage to properly power the
LEDs.
For 12V input voltage, the current drain will be around 1.8A at full load (18W).
