Review: B3603 DC-DC Step Down Module from Banggood

The B3603 is a digitally controlled cheap DC-DC board providing constant voltage and current limit. It accepts 6 V to 40 V input and outputs from 0 V up to Vin minus 2 V. It can support up to 3 A, but not without additional cooling. I tested 1 A without problem, other sources reported 2 A as usable maximum.

How to return to factory settings?

[@mitropoulosilias]

mine have blown i do not know why. it was working and then not working

[@lenaroseguera1241]

what's its power?

[@RoboUlbricht]

3A max.

[@lenaroseguera1241]

I was meaning the wattage. (max voltage * max amperage). (30Vmax * 3Amax = 90watts ???) what's the maximum current at 30v?

[@RoboUlbricht]

You are limited with small heatsink. It is hot at 12 V and 1 A. So practical power limit will be 15-20 W. It is just my opinion. More power can deliver B3606, which has bigger heatsink.

ok thanks so much
