PI2211: Recommended Design Steps

There are two options to designing a hot swap solution with the PI2211:



Utilize PICOR's PI2211 reference design with pre-selected components



Follow PICOR's design guidelines and use the "Picor Calculator Tool" available from Picor's website

Either of these approaches will yield a suitable and reliable hot swap design solution.

Figure 13 - Final Design Schematic

For this design example we'll define our system requirements as follows:













Hot-Swap Efficiency > 99%



Schottky Diode is 40V, 1A; required to protect the SCR pin from negative voltage transients that can damage the controller.

The 100Ω series resistor is used to limit current.
