# LED strip buck converter
|

|
|
|
This is a daisy-chainable buck converter for 12 mm wide LED strips with 2
|
|
|
|
control pins, e.g. APA102. It is designed for 4 amps of output current at 5V,
|
|
|
|
which is enough for about 60 LEDs (plus some safety margin).
|
|
|
|
|
|
|
|
The converter can be soldered between two segments separated by a few
|
|
|
|
millimeters, with an additional two wires between each two sequential
|
|
|
|
converters for the source voltage - the IC supports 6 to 28 volts, but the
|
|
|
|
circuit was designed with 24V in mind.
|
|
|
|
|
|
|
|
The bottom of the PCB has a space for an optional 3v3 to 5v level shifter,
|
|
|
|
allowing you to directly feed it from microcontrollers that do not use 5 volts.
