PIN FUNCTIONS EXTV + CC (E12):
External power input to an internal control
VOSNS (J12):
(+) Input to the Remote Sense Amplifier. switch allows an external source greater than 4.7V, but less This pin connects to the output remote sense point. The than 6V to supply IC power and bypass the internal INTVCC remote sense amplifier can be used for VOUT ≤ 3.3V. LDO. EXTVCC must be less than VIN at all times during Connect to ground when not used. power-on and power-off sequences. See the Applications
V – (M12):
(–) Input to the Remote Sense Amplifier. Information section. 5V output application can connect the
OSNS
This pin connects to the ground remote sense point. The 5V output to this pin to improve efficiency. The 5V output remote sense amplifier can be used for V is connected to EXTV OUT ≤ 3.3V. CC in the 5V derating curves. Connect to ground when not used.
VOUT_LCL (L12):
This pin connects to VOUT through a 1M
DIFF_OUT (K12):
Output of the Remote Sense Amplifier. resistor, and to VFB with a 60.4k resistor. The remote sense This pin connects to the V amplifier output DIFF_OUT is connected to V OUT_LCL pin for remote sense OUT_LCL, and applications. Otherwise float when not used. The remote drives the 60.4k top feedback resistor in remote sensing sense amplifier can be used for V applications. When the remote sense amplifier is used, OUT ≤ 3.3V. DIFF_OUT effectively eliminates the 1MΩ from VOUT to
