Using the LTC3810-5 synchronous step-down switching regulator controller can be designed a very easy and simple 12 volt switching power supply electronic project using few external electronic parts . LTC3810-5 synchronous step-down switching regulator controller can directly step-down voltages from up to 60V, making it ideal for telecom and automotive applications. The LTC3810-5 uses a constant on-time valley current control architecture to deliver very low duty cycles with accurate cycle-by-cycle current limit, without requiring a sense resistor.
Using the LTC3786 high performance synchronous boost converter controller that drives all N-channel power MOSFETs can be designed a very simple and high efficiency 25 volts DC at a maximum current of 5 amperes .
Synchronous rectification increases efficiency, reduces power losses and eases thermal requirements, allowing the LTC3786 to be used in high power boost applications.
This power DC converter electronic project require an input voltage range between 5 and 24 volts DC.
Using the ISL9440 quad-output synchronous buck controller IC can be designed a very simple high efficiency electronic circuit power supply, that will provide 4 different fixed output voltages . ISL9440 synchronous buck controller circuit integrate 3 PWM controllers and 1 low drop-out linear regulator controller, which are full featured and designed to provide multi-rail power for use in products such as cable and satellite set-top boxes, VoIP gateways, cable modems, and other home connectivity products as well as a variety of industrial and general purpose applications.
