SOLDER PAD NOTES:
[1] To avoid incorrect contacts with exposed via’s and plated through holes on the bottom of the converter, do not have any
exposed copper around the unit aside from our recommended footprint. Except for connections to the pads, keep all external
circuits away from the board edges.
[2] Do not connect any additional components between the Trim pin and Vout or between the Trim and Sense pins. Use only
the specified connections.
