I thinks you might something the circuit that has the height and economize with.I begs for to advise this circuit , because use voltage regulator Ic 78XX series series. By you can change Voltage get follow want,– 5V = IC 7805 (5v voltage regulator), – 6V = IC-7806 – 8V = IC-7808 , – 9V = IC-7809 , – 10V = IC-7810 , – 12V = IC-7812 such as. By still use PCB and other equipment as before. To use transformer 1-2A. IC-78xx to Hold Heatsink.For example circuit that use IC-78xx series in fixed voltage supply for digital circuitsI am built this dc regular circuit, is the first project. Because at that interesting about digital circuits, need a constant 5V 1A fixed power supply. Using IC-7805 is very suitable for this job. Because it is easy to use, easy to buy, as popular applications, and it is also cheap. For working principle, I would permitted to tell simply. When the home electric source ACV, 110V or 230V or a 220V, depending on your country, through the transformer, the voltage remains 9VAC.

Then through the diode for rectifier power supply to the DCVolt, And a filter circuit with Capacitors. This is a voltage is about 12Vdc. It does not work through IC-7805, before our hero, for to control a stable 5V voltage with can prevent also a short circuit. Just now I have a small circuit great ready to use it. The PCB layout of Power Supply 5V 1A by IC 7805 and The all components layout. The main parts of this circuit is IC 7806,It is normal IC linear dc voltage regulator 6V at 1A current. It is easy project electronic because used the minority part and low cost too. I have of a 9Vac 1A transformer,The output of the transformer is rectified by diode 1N4001 or equivalent to more high power, Thence to smoothed filter using 470uF 35V capacitors,so the volt this is unregulated DC voltage have value 11V-12V DC. Besides must use this ic with a suitable heatsink. Detail more,Please in image circuit.           Eleccircuit highly recommends EasyEDA for PCB design and orderAC-DC Converter Chips Information

Show all AC-DC Converter Chips Manufacturers AC DC converter chips adjust AC input into DC output. These chips have a specific integrated circuit (IC) package type. How AC DC Converter Chips Work AC DC converter chips rectify AC input into DC output. They also adjust the voltage level through a regulator and smooth the pulsating DC through a capacitor. This video explains AC to DC conversion. Video Credit: Jeffrey Regester / CC BY 3.0 Types of AC DC Conversion Chips Linear AC DC converters are inexpensive and simple. A disadvantage of the device is they are inefficient since they siphon off excess power as heat. SMPS (switch/switched/switching-mode power supply) shift very quickly between full-on and full-off states via a switching regulator (using transistors such as BJTs, MOSFETs, or IGBTs). This minimizes wasted energy. They are also smaller and lighter. However, switching converters can cause electrical noise problems and may have a poor power factor.

Important specifications when selecting AC DC converter chips include, AC input range (e.g., 85-264 VAC) or are set (e.g., 115, 208, or 230 VAC only). Output of DC can be specified with respect to watts (e.g., 3 to 1,000), volts (e.g., 3 to 380), and amps (positive or negative; 1.6 to 6,000). Operating temperature allowances are bracketed (e.g., -20 to 70 C). AC DC converter chips feature several main characteristics such as, Converter chips can have one or more outputs. Protection add-ons include overcurrent, overvoltage, or short circuit. Power factor correction is available to counteract distortion and raise the power factor. These chips may be switched on/off remotely. The device containing the converter chip can be ruggedized. Converter chips are found in cell phone chargers, computers, and other electronic consumer devices. They are also used for industrial machinery, as well as medical, military, and telecommunications equipment.
