Error Amplifier: Figure 2 shows error amplifier biasing, applied input voltage must be set within the range
of common-mode input voltage (1.8 V to 3.4 V). Inserting a resistor and capacitor between phase
compensation terminal (pin 9) and GND in series provides phase compensation.
Current Limiter: The sense amplifier threshold voltage (V

) for the current limiter is:
