Six output DC regulator using LTM8008
Using the LTM8008 μModule SEPIC converter with six post regulators can be designed a very simple compact power supply electronic project , that has six outputs that can provide different output current for some of outputs .
The SEPIC controller’s fixed frequency, current-mode architecture results in stable operation over a wide range of supply and output voltages and features soft-start and frequency foldback functions to limit inductor current during start-up and output short-circuit.
The output voltages of the LTM8008 are : one 5V at 500mA, one 3.3V at 300mA, and four 5V at 150mA.
The output of the SEPIC controller is internally set to 5.6V for optimal efficiency.
In addition to providing these outputs, the SEPIC converter can supply up to an additional 500mA to the system load.
As you can see in the circuit diagram , this electronic project require few external electronic parts .
For powering this electronic power supply circuit you can use a wide range input voltage from 3 volt up to 72 volts .
For the L1 (4.7uH) coil you can use a COILCRAFT MSD1278T-472ML coupled inductor type .
