SMPS SCHEMATIC
Power Part.
  This part consists of the one 3.3V, and one 1.8V regulators to convert power which is provided 5V in Power board.  16V is provided for inverter, 16V is provided for LCD panel and 5V for micom.  Also, 5V is converted 3.3V and 1.8V by regulator. Converted power is provided for IC in the main board.  The inverter converts from DC16V to AC 700Vrms and operates back-light lamps of module.

TL594 12V DC Switch Mode Power Supply Circuit Diagram

In recent years, the use of switch mode power supply (SMPS) has become more comon as more applications demand for greater power eficiency. It makes use of semiconductor (mostly MOSFET) fast switches to switch DC input that has been rectified at high frequency. The advantages of high frequency switching are that it reduces the size of inductor, capacitors & transformer used. Other advantages of switching power supply over linear power supply are : 1) High Efficiency (up to 90% and above for nice design). 2) Output can be higher than input. 3) Able to operate over a variety of input power supply. 4) Able to have over output. The setback of using SMPS compared to linear power supply is that it generates electrical noise which contributes to electromagnetic compatibility design issues & more part count. Buck Converter SMPS The SMPS circuit below from Power Integration makes use of LNK304 as its high frequency switch. Take note that this circuit is non isolated type which means tha

Latest TDA2030 Complete Tone Control Circuit Diagram

Image
This is the Simple IC TDA2030 Complete tone Control Circuit Diagram . This circuit that use IC TDA2030, but this series is equipped with a tone control. Tone controls include Bass, Treble, and Volume. Power amplifier and tone control has been put together in a single PCB. This amplifier is a mono amplifier type, can be modify for guitar amplifiers .  If not coupled amplifier (mic preamp) then you must deactivated potensio treble and bass, why? because if not using a mic preamp and still maintain potensio treble and bass sound input (input) from the guitar will not or the maximum discharge is not tight on the speakers . So you must deactivated a way to decide which directly connected capacitor  with the tone control circuit, and capacitor were connected directly to potensio volume and input jack.   TDA2030 Complete Tone Control Circuit Diagram PCB Layout   TDA2030 Complete Tone Control Circuit Diagram PCB
