How to #2 - Use LTC3780

This is a Buck Boost converter, which is a kind of high efficient power supply module with Constant voltage, constant current, under-voltage protection.

What is Buck Converter ?

It can step down the voltage

What is boost converter ?

It can step up the voltage

And This LTC3780 is Buck boost converter !

Step 1: What Are These Pots ?

Far right one is for Under voltage protection (VV) and it is mostly used for Solar Charging

What does it mean ?

The device can monitor a DC-DC output voltage and quickly disconnect the power source from the DC-DC input load when an overvoltage condition occurs. A power-OK output signals when the DC-DC input voltage falls below an adjustable threshold.

Center one is for Constant Current ( CC)

What does it mean ?

A constant current is that does not change its intensity with time.

Left one is for Constant Voltage ( CV )

What does it mean ?

Same as CC does not change over time

Step 2: How Much Power Can It Handle ? and Efficiency ?

It depends on the board the one which I have used can handle Up to 130W

But after 80W it needs to increase the Heat Dissipation

And

The sweet spot for the efficiency is 98% at 12V

Step 3: Lets Power It Up !

I had a bunch of LED's soldered in parallel

After powering it up I have to say it worked like charm and I was able to control the voltage and current to change the intensity of the LED's
