GETTING STARTED
SETUP PROCEDURE
Chapter 2. Installation and Operation
The MCP1630 Sepic Automotive LED Driver Reference Design is fully assembled and
tested. The board requires the use of an external input voltage source (9V to 16V) and
an external LED load, provided by Microchip.
2.1.1
1. A DC power supply, a bench supply that can produce 12V, 2.5A, is recommended
2. An oscilloscope and/or a multi-meter to observe the waveforms and measure the
To operate the MCP1630 Sepic Automotive LED Driver Reference Design, the
following steps must be completed:
1. Attach an LED load (or dummy load) to the Output Connector J3 (observe the
2. Attach the push button to the J1 header (between Pins 3 and 4 is optional).
3. Connect a power supply to the Input Connector J2 (observe the polarity).
Detailed instructions are provided below for each step.
2.2.1
The board is configured to deliver a maximum of 350 mA to the LEDs’ load. UVLO and
OVLO thresholds are set to 8V and 17V, respectively. The maximum output voltage is
set to be approximately 55V.
2.2.2
A string of up to sixteen white LEDs (1W each) can be powered by this board. The
LED's string must be mounted on an appropriate heat sink to keep the maximum
junction temperature at safe level (consult the LED data sheet for details). The
maximum current delivered by the board to the LED's string is set to 350mA and the
maximum output voltage is 55V.
(dummy load). In this case, the power delivered to the load will be about 18W.
Connect the LEDs’ string to the J3 connector. It is very important to use the correct
polarity (see Figure 2-1).
Please observe the polarity for all steps to avoid board damage.
The LED's string can be replaced by a resistor of 150Ω and 20W dissipated power
to operate the board at the full rated power.
