12 volt switching power supply using LTC3810-5

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.

A precise internal reference provides 0.5% DC accuracy. A high bandwidth (25MHz) error amplifier provides very fast line and load transient response. Large 1Ω gate drivers
allow the LTC3810-5 to drive multiple MOSFETs for higher current applications. The operating frequency is selected by an external resistor .
This 12 volt switching power supply electronic project based on LTC3810-5 synchronous step-down switching regulator controller will support a maximum output current up to 6 amperes with a high efficiency , more than 95 percent .
Constant on-time current mode architecture provides accurate cycle-by-cycle current limit protection—a feature that is very important for protecting the high voltage power
supply from output short circuits.
As you can see in the circuit diagram , this 12 volt switching power supply circuit require few external electronic parts , thing that make it ideal for compact power supplies applications .
