A technical talk about this 5 volt regulator. It's a high efficiency high current synchronous rectification DC/DC buck converter with a really tasty high current inductor. Watch me destroy it in front of your eyes!

Could the other one you are going to replace it with be used to power a raspberry pi 4? As it has a usb output.
about the protecting diode: 0.2V drop at Vcc = 20V (not 5V Vout) is only 1% loss in efficiency, all is good 🙂
Thank you for the review. You break it to show us. You damaged for the sake of viewers benifit. Thank you.
someone help me please. I want to buy voltage regulator and the two i came across uses MP1484 and lm2596. Can anyone tell me which one should i buy. I want to step down voltage to 5 volts for solar usb charger.
Нормальный такой – для 3 устройств как блок питания в автомобиле использую
MOSFETs with eight legs? WTF
hi Julian, thanks for the video. Now that you know much about tech, where can I find a 12v to 5V 2-3A continual, meaning it will never reach 1A but where 2-2.5A is the minimum? Need it for a project, thanks you in advance!
The coil is a strip of copper and Julian destroyed it.
I never thought Julian would "do a strip" in public…

so can two "Synchronous Rectification Buck Converter" be parallel with around 50% load balancing?
Actually I want to make battery charger for lithium ion battery. I want to charge 10 batteries at time and I have transformer of 12v and 5A step down. so could I give the 5A supply to this module. Suggest me any module to which I can give the input voltage of 12V dc and 5A and at output I want 5V and 5A
can we give the input supply current of 5A to this module
The module itself consumes about 20mA with no load. So its efficiency is questionable in low current circuits.
boss why you didn't test it before you destroy??? shame,..
Argh! Techy tears flowing – but you are right, nice piece of gear.
I just got few of those. The frequency is about 260 kHz – not that high as you would think with such a small inductor. This means that it won't work as well at low currents (bigger ripple). The ripple at 170mA is 80-100 mV. In comparsion the LM 2596 ripple is 20-30 mV in similar conditions without additional filtering. Another problem is that both input and putput pass the whole PCB and create an inductance that picks high frequency content (quite sharp impulse) from the coil. I would connect input and output to the opposite side right on the capacitors by scratching the solder mask. Also I will addd aditional filtering. I still haven't measured the efficiency. I have to remove the diode and the LED before I do that.
