disables the LTC3240-3.3/LTC3240-2.5. This pin is a high
impedance CMOS input pin which must be driven with valid
logic levels. This pin must not be allowed to fl oat.
Exposed Pad (Pin 7): Ground. The exposed pad must be
soldered to PCB ground to provide electrical contact and
optimum thermal performance.
