2A DC / DC buck converter test with regulation and voltage and current display

TechEkspert 22 Mar 2018 18:05

Soon on elektroda.pl there will be a DC / DC step-down converter module with output voltage adjustment by buttons and output current measurement. Measurements and settings are presented on the backlit LCD display. Maximum input voltage 23V (recommended 20V), output voltage adjustable in the range of 0-16.3V, maximum output current 2A (temporary 3A). The set includes a transparent plexiglass housing. The module has no additional heat sinks beyond the board surface.

More than 1Vpp of ripple at 5V is a massacre [Read more]

AVE ... I have this module but I don't use it anymore. Lack of current limitation disqualifies it in workshop applications. In addition, the factory power connectors suck, I advise you to desolder... [Read more]

In my opinion, after watching the oscillograms, this converter is not of good quality. With no load, ripple pk-pk 150mV and such pins, the converter probably shines well. I wonder if it meets EMC standards. ... [Read more]

A few weeks ago, there was also an inverter in GADGETS, but in my opinion it was much better, because it had an output voltage range of 0-30V, and output current adjustment. The only downside was the lack... [Read more]

@ szymon122 there is no diagram, the modules are e.g. here: https://pl.aliexpress.com/item/Diy-kit-DC-DC-adjustable-step-down-Regulated-power-supply-module-Belt-voltmeter-ammeter-Dual-Display/32805760120.html ... [Read more]

AVE ... The connectors are of extremely crap quality, February also did not hurt the ass. After the fourth time the wire fell out, I desoldered these connectors and fired. Now I do not use this power... [Read more]

Maybe some sensible capacitor at the output would help? Just by the eye, after the photos (for spite all from the same angle ;) ), there is nothing specific there except a tiny MLCC. Maybe someone took... [Read more]

With such ripples, I do not know what can be powered with it. Probably some kind of heater :P [Read more]

Right out of the box, it's actually a drama. Maybe a matter of looking at what the executive system is and calculating the components. Maybe someone was counting on the knee parameters for a specific... [Read more]

Or a light bulb. I powered a raspberry pi of a similar construction with a converter (only without LCD, also ali). I was surprised, despite the 5A's performance, Rpi was able to freeze or project... [Read more]
