this is super. i wish i would have seen this yesterday. i exploded my mini lamps because i didnt know that they can be adjusted. this was excelent learning!
The ic is out of patent so now the "original" manufacturer has stopped making them , however chinese ic manufacturers are now able to make them without copyright infringement , so they are not actually obsolete. Secondly , the recommendation of not using them in new designs comes from the original manufacturer who have made "new" buck converters that run at higher switching frequencies , again this is just marketing and when the "new" ics are out of copyright they will then be labeled not for new designs. I have a mini 360 using a mp1482 ic,so there are other ics to use,also the ic is rated at 3A continuous,the ebay sellers list them at a lower continuous rating because the pcb has limited vias and or heat sinking for the full current rating of the ic. I am going to integrate the ic into some of my own designs using the mini360 circuit but not the actual module as the circuit is easy enough to reproduce into a design and uses far less space on the main pcb than the LM2596 i originally designed for, considering the pcb area is a fixed size for a type of enclosure used,i also like making my own circuits in this manner , though if the module suits your needs then have at it.
Do you still use it? I bought this speaker as a second hand from a local market. It was dirt cheap. Honestly, I don't use it but it was a good fit for the simple demo in this video.
@@usmanumer9871 btw today I published a new video about USB-C Power Delivery (PD) for voltages higher than 5V DC. I am still experimenting with various PD sink chips. Eventually, in distant future I might convert a similar old speaker to a USB-C powered device :)
Use a normal lm type regulator , or make a precision regulator with an op-amp and a transistor suited to current needs , a SO8 741 op-amp is tiny and is mounted smd , while a through hole transistor can be mounted on the non copper side flat making for a very small pcb design with variable current and voltage if needed using smd trimmer pots. Even if you need little current a zener shunt design gets even smaller.

Thanks for the feedback. I am happy to hear the video is useful!

Thanks for sharing these details. Speaking of LM2596, yes it is a good alternative if PCB space is not constrained.
Could I put 24v in the input voltage and output 5v? I just need to use it for a 5v fan.
No, according to the technical data I saw the supported and recommended input voltage is no more than 23V.
i had similar speakers back in 2009

@@LeonAnavi I don't have it now

@@LeonAnavi nice idea
pm me can you install do solar panel of charger.
What if i give input 4v, can i reduce to lower than 2v?
Probably not a good idea for 4V because as far as I know the input voltage is in the range 4.75V to 23V.
