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 specifi ed connections.
