Power Supply circuits diagram electronics projects

Using the LTM4627 integrated circuit designed by Linear technology you can design a very simple , high efficiency 15A switch mode DC/DC power supply.

The LTM4627 power supply circuit include in the package almost all components required : switching controller, power FETs, inductor and compensation components , this high power switch mode DC regulator IC require few additional external electronic components .

This switch mode power supply circuit require an input voltage range , between 4.5V to 16V,and will provide a very stable output voltage of 1.2 volt . The LTM4627 supports an output voltage range of 0.6V to 5V, set by a single external resistor , so you can modify the output voltage .
High switching frequency and a current mode architecture enable a very fast transient response to line and load changes without sacrificing stability.

Using the NJM2391 we can design a very simple high efficiency , high precision power supply circuit that can be used in small applications ( for example in Notebook PCs, PC cards and hard
disks ) . NJM2391 power supply circuit is very easy to design , requiring few external components .

If you want to design a high precision power supply or a high precision voltage reference circuit , the NJM2391 regulator can be your choice , because it can provide an output voltage between 2.5 volt and 5 volt .

The maximum output current that can be provided by this circuit is around 1A .
Some of the main features provided by this power supply circuit are : low dropout voltage ,internal excessive voltage protection circuit , internal short circuit current limit , internal thermal overload protection.

A very simple high efficiency switching mode buckboost power supply circuit can be designed using the LTM4609 switching regulator IC . This switching power supply circuit will provide an fixed output voltage of 32 volt . As you can see in the schematic circuit , this switching power supply circuit require few external electronic components .

Included in the package are the switching controller, power FETs and support components.
LTM4609 supports an operating input voltage range of 4.5V to 36V and supports an output voltage range of 0.8V to 34V, set by a resistor. This high efficiency design delivers up to 2A continuous current in boost mode .

Only the inductor, sense resistor, bulk input and output capacitors are needed to finish the design.
The high switching frequency and current mode architecture enable a very fast transient response to line and load changes without sacrificing stability. The LTM4609 can be frequency synchronized with an external clock to reduce undesirable frequency harmonics.
Fault protection features include overvoltage and foldback current protection.
For this LTM4609 switching power supply circuit project you will require an input voltage range between 8 and 36 volt .
