tive 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 1 © gate drivers 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 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.
