Then test them with 12V battery at input and measure voltage ouput will have about 22V please watch as video below. PCB of DC to DC converter using TDA2004 the component-layout-of-DC to DC converter using TDA2004 After examining the faulty circuit. To determined working of IC1.īuilding,Testing and Application When we are fully equipped and built PCB as Figure below and then soldering equipment, as Figure. The capacitors C1-C4 acts as square wave generator about 5 Khz. Hdclone Enterprise Edition 16x Serial here. And the working of circuit will return to the first time.Īnd when current out of pin 8 and pin 10 to Converge together at C6, cause output have voltage rises up one times. So the current flows to the D3 and C6, the voltage at pin 8 so drop near zero. The capacitor-C7 so charged instead by through the input power supply. But at output of circuit will have voltage equals the input power supply.Īt this point, pin 8 of IC1 (output of IC1 / 2) So begin have thec voltage rise instead. The power supply has a current flowing through D2 and C6, Until the pin 10 of IC1 / 1 has a nearly zero. Circuit diagram of DC to DC step up converter using TDA2004. This voltage will get from charging of capacitor-C5 through diode-D1 cause have voltage increased about 2-fold. The working principle As soon as, We feed the input pin 10 of IC1 (output of IC1/1) It starts with high voltage up. This circuit is not necessarily the coil and the device easily. We use an IC amplifier features the original, is producing a high current frequency to store a voltage in the Capacitor is about 2 times the input. Or from 12 volts to 24 volts with a simple model of The DC to DC step up converter circuit with use TDA2005 or TDA2004 as main. DC to DC step up converter using TDA2004 or TDA2005 We can increase the DC voltage from 6 volts to 12 volts. Or It can enhance voltage double, be 2 times there.ĭetail to See Circuit. By drive high current with power mosfet BUZ11 make output current collect at capacitors the very total up voltage bilateral the group then is double of Input power supply. It use the integrated circuit digital number perform produce the frequency drive current change bilateral the group trips work. This circuit has can to help you by it has prominent easy good point. But want to enhance voltage be 24V or about 2 times. If you have power supply source about 12V, from battery 4A sizes. For input DC12V-24V 4A to Output 24V-48V 2A (inputX2) Use easy circuit simple part IC Digital Cmos: 40106 and Mosfet BUZ1. The block diagram above shows the working of the UCD3138128 device on the Bidirection board.ĭC/DC Converter DC12V to 24V 2A by IC 40106 and Mosfet BUZ11 This is Circuit DC to DC Converter. The vehicles nowadays are trying to adopt a 48 -12 volt system to increase their. 2.1.3 Current feedback circuit check and calibration.
