DESCRIPTION
Feedback Pin for the Buck Regulator. A resistor divider from the regulator’s output to
the FB pin programs the output voltage. Servo value for this pin is 0.6V.
Pulling the MODE pin low allows buck operates in PWM mode at high load currents
and in PFM mode at light load currents. Pulling the MODE pin to high or floating
enables the power save mode.
