DC To DC 5V 3A Buck Converter Circuit Diagram, or 3A DC Smartphone Charger Circuit Diagram

 DC To DC 5V 3A Buck Converter Circuit Diagram, or 3A DC Smartphone Charger Circuit Diagram. LM2576T-5.0, Battery mobile phone charger circuit board build; by "AMKP40 technology".



This is a very powerful DC to DC 5v buck Converter circuit using LM 2576T -5.0 switching step down voltage regulator IC this IC provide Max 3A output and produce low amount of heat comparing other linear voltage regulator, like LM317 or LM7805.

This circuit can charge your smartphone easily and very reliable to use, because in this IC have over voltage protection using feedback function inbuilt. You can drive this circuit any voltage between 7 Vot DC to 40 Volt DC this can still provide you 5 Volt DC in output.

How to make 3.7 volt Lithiun-ion Battery chager with full charged indicator without IC. By AMKP40 technology. This circuit work perfectly with 5V DC adapters and 3.7v lithium-ion battery. If battery is fully charged with 4.267v than RED LED turns off that means battery is fully charged. If you want fast charge your battery, you just change the resistor behind this diode. Also you can  adjust which voltage you want to show battery is fully charged, just rotating the 1K veriable resistor. This circuit Diagram is personal of AMKP40 technology [YouTube Channel].
