Connect the feedback resistor divider tap to this pin. Also, connect a phase lead capacitor between FB and the output. Typically, this capacitor is 10pF. SS (Pin 2): A capacitor is tied between SS and ground to slowly ramp up the peak current limit of the LT3995 on start-up. There...
FB (Pin 4/Pin 5): Feedback Input to the Error Amplifier of the Step-Down Regulator. Connect a resistor divider tap to this pin. The output voltage can be adjusted from 0.6V to VIN by: VOUT = 0.6V • [1 + (R2/R1)] For Fixed VOUT options, connect the FB pin directly to VOUT...
PG remains low until the FB pin is within ±9% of the final regulation voltage, and there are no fault conditions. PG is valid when VIN is above 3.4V, regardless of EN/UV pin state. FB: The LT8620 regulates the FB pin to 0.970V. Connect the feedback resistor divider tap to this ...

Connect the feedback resistor divider tap to this pin. The two FB pins on the MSE package are connected internally and provide a redundant path for the feedback divider. Tie the divider to both pins. VOUT (Pins 1, 2, LT3990-X Only): The LT3990-3.3 and LT3990-5 regulate the VOUT ...
Connect the feedback resistor divider tap to this pin. TR/SS (MSOP Only): Output Tracking and Soft-Start Pin. This pin allows user control of output voltage ramp rate during start-up. A TR/SS voltage below 0.778V forces the LT8606 to regulate the FB pin to equal the TR/SS pin ...
