A very simple high efficiency 12 volt power supply electronic project can be designed using the LTC4444 high frequency high voltage gate driver that drives two N-channel MOSFETs in a synchronous DC DC converter with supply voltages up to 100V.
LTC4444 driver reduces switching losses in MOSFETs with high gate capacitance.
This 12 volt power supply electronic project use a LTC3780 high efficiency buck boost controller circuit a LTC4444 driver and some other common electronic parts .
A very simple dual 15 volts power supply electronic circuit project can be designed using the LT3512 switching regulator IC manufactured by Linear Technology .
LT3512 is a high voltage monolithic switching regulator specifically designed for the isolated flyback topology.
The device integrates a 420mA, 150V power switch, high voltage circuitry, and
control into a high voltage 16-lead MSOP package with four leads removed.
A very simple LNB power supply electronic circuit can be designed using the ISL9492 a highly integrated voltage regulator and interface IC specifically designed for supplying power and control signals from advanced satellite set-top box (STB) modules to the low noise blocks (LNB) of a single antenna port.
This circuit is very simple and require few external electronic parts ( as you can see in circuit diagram ) .
