I am using the LTC3330 simply as a buck converter for now. I don't intend to use the buck-boost converter and shall be tying its input BAT (Pin #16) to GND. My questions are,
1) Can Pins #14 and #15 be kept floating ? (I want to avoid the buck-boost converter's inductor connected between these two terminals).
2) Since I am not using buck-boost, can I simply GND the Pins #17, #18 and #19 used to selected the limiting current for the buck-boost converter ? In the demo-board (DC 2048A), these pins are tied to GND via three zero Ohm SMD resistors ? Is it necessary to use these resistors ?
