85% efficiency SMPS circuit

Posted on Feb 6, 2014

The circuit is quite simple thanks to the use of MAX638CPA 5V CMOS Step Down Adjustable Switching Regulator IC. With this IC input voltage of 12 to 16 Vdc converted into direct voltage 5VDC. You can see here is only using 9 additional external components to complete the circuit. The schematic diagram come from circuit: Switch Mode Voltage Regulato

r with 85% efficiency power supply. Go to that page to read the explanation about above power supply related circuit diagram. Switch Mode Power Supplies (SMPS) is now widely used in modern electronic equipment due to its compact design and high efficiency of about 80% or more. The switch-mode regulator circuit presented here has an efficiency of around 85%. The circuit. This simple switching regulator circuit have 5 V output, the input provide by a 9 V battery. It having 80% efficiency and 50mA output capability. How simple switching Regulator works: While Q1 is actually on, its collector voltage increases, delivering current. To supply the high voltage converter suitable source of alternating voltage 12 V / 800 mA. An alternating voltage is rectified by a diode bridge with an allowable current of 1 A. Converter output voltage is adjustable between 0. . Laptop display commonly apply large screen Lcds, which generally will need a adjustable and a negative supply to ensure highest possible contrast. This circuit works with the system`s positive notebook battery supply and generates a digitally adjustable negative voltage to. Built a PC power supply basically quite simple. It consists of a housing made of metal. A Euro unit connector is for connecting to the socket, and there is a power switch. The PC power supply has at least one.
