error amplifier is set up as a proportional gain amplifier
as shown in
The devices incorporate an error amplifier with a 1% pre-
cision voltage reference that enables negative feedback
control of the output voltage. The output voltage of the
switching converter can be programmed by selecting the
values for the resistor-divider connected from V
the flyback /boost output to ground, with the midpoint of
the divider connected to the FB pin

The devices include a robust overcurrent protection scheme
that protects the device under overload and short-circuit
conditions. A current-sense resistor, connected between
the source of the MOSFET and PGND, sets the peak
current limit. The current-limit comparator has a voltage
