Linear and switching power supplies circuits design

Linear and switching power supplies electronic circuits design projects and schematics.

12 volt power supply using LTM4096

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 12 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.
For this switching power supply circuit project you will need to use an input voltage range between 5and 12 volt .

LT3741 10V 20A power supply

Using the LT3741 fixed frequency synchronous step-down DC DC controller you can design power supplies applications that require a maximum current up to 20A. The LT3741 is manufactured by Linear technology and will maintain inductor current regulation over a wide output voltage range of 0V to (VIN – 2V). The LT3741 DC-DC controller IC operate over a wide input range , from 6 volts up to 36 volts . The regulated current is set by an analog voltage on the CTRL pins and an external sense resistor.
