Using the LTC3869 high performance dual synchronous step-down switching regulator controller that drives all N-channel synchronous power MOSFET stages can be designed a very simple and efficiency high current power supply circuit that will provide 12 and 5 volt output voltage . This LTC3869 dual output power supply electronic project accepts a high range input voltage between 13 and 38 volts . A constant frequency current mode architecture allows a phase-lockable frequency of up to 780kHz.
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.
