Function
Internal LDO Output;
Used for internal biasing and gate drive. Do not leave open, bypass with external
capacitor. Do not connect other circuitry to this pin.
Switch Output;
Connect to the gate of external boost converter switching MOSFET.
Current Sense Ground;
Ground return for current sense switch, connect to bottom side of sense resistor.
Current Sense Input;
Detects the peak current through switch, connect to high side of sense resistor.
Soft Start;
Connect an external capacitor to adjust the soft start ramp, do not leave open.
Feedback;
Output voltage feedback, connect to output voltage via resistor divider from output
capacitor to ground.
Not Connected;
Compensation Input;
Connect R and C network to improve the stability of the regulation loop.
