A first look at this high efficiency (up to 98%) high current (10A) DC/DC converter employing 4-switch synchronous rectification. Based on the LTC3780 controller IC.

I saw this video a few years ago and it convinced me to get the ltc3780 it has proven to be a primary staple and a true workhorse it is amazing.
Im seeking advice from you on how I can parallel two of them together for a dual supply. I've tried a few different configurations but the boards go into protect mode and could use some advice please.
The module is 5A max not 10A , and max current of diode SS54 is 5A , so the module at 5A is ok but more than will fail and dead.
Hi Julian. Where can one get one of those very handy trimpot screwdrivers?
Put a 24 volt supply behind that and put some potentiometers where those multi-turn pots are and you have got a decent little bench power supply
Can anyone in the comments recommend a circuit board that starts out 12V and then switches that same output to 5 V and holds steady till i turn it off?? I Just need 12 v for a second or two Then hold 5v indefinately.
Last I heard, graphite was conductive?
The third trimmer is used for mppt or maximum power point tracking it is used for solar cells np
Hi Julian- I'm looking for a DC to DC boost converter to power my laptop while in my caravan from the 12V battery. The specs for the AC wall charger that comes with my laptop state it requires 20V DC at 6.75A. Do you think the 3780 boost converter is capable of powering a laptop for these conditions?
Hi Julian where did you get your RYOBi multimeter please??
Hello Sir, How can the LTC 3780 be used to charge Battery and be connected to Load at the same time The LTC3780 board does not show have a separate connection to load. Kindly explain how I can charge a 12volt batery and also connect to Load at the same time such that load is being supplied with a 12 volt while the battery is also being charged. Any assistance will be appreciated.
You can get one with a heat sink, and it will have a better build quality on eBay vs company’s like ali and amazon.
You are amazing
I have been using this buck boost converter for awhile with a 9v battery being the input and the output 12v.
Do you think I could use a LiPo battery instead of a 9volt battery or is the input voltage going to be too low?
