LTC3810 12 volt switching power supply

A very simple 12 volt switching power supply electronic circuit can be designed using the LTC3810 synchronous step-down switching regulator controller that can directly step-down voltages from up to 60V.
The LTC3810 12 volt switching power supply 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.
This switching power supply electronic circuit require few external electronic parts and has a very high efficiency , more than 95 % .

The operating frequency is selected by an external resistor and is compensated for variations
in VIN and can also be synchronized to an external clock for switching-noise sensitive applications .
In put voltage required by this power supply electronic project can be from 13 volts up to 60 volts . The circuit will provide a fixed 12 volts DC output voltage at a maximum output current of 6 ampere . Thanks to wide input voltage range and high output current , this circuit can be used in various applications like Telecom and Base Station Power Supplies , Networking Equipment or Automotive and Industrial Control Systems .
