Applications Information
The following designs are provided as reference circuits. For a specific design, the steps in the Design Procedure section should
be performed. In all designs, an RC filter (0.1 µF, 10
Ω
) is recommended at VIN placed as close as possible to the LM3424 device.
This filter is not shown in the following designs.
