In this example, the designer wishes to find the correct inductor for a continuous mode buck converter, changing an unregulated 12VDC source to 5VDC regulated. The max load current is 1.0 amp. Using the Inductor Selection Graph for 5.0V fixed applications, simply follow the 12 volt horizontal line until it intersects with the 1.0 amp vertical line. Customers can see this is within the 68 micro Henry region, and the inductor code is L30. The next step is to find the appropriate inductor part number from the Inductor Chart. This inductor will be properly rated for both load current and energy storage.
