NAME
FUNCTION
1
SUPPLY VOLTAGE
Unregulated voltage input. An internal regulator powers the
internal logic.
2
FEEDBACK INPUT
The feedback terminal of the regulation loop. The output is
connected directly to this terminal for 5.1V operation; it is
connected viaa dividerfor higher voltages.
3
FREQUENCY
COMPENSATION
A series RC network connected between this terminal and
ground determines the regulation loop gain characteristics.
4
GROUND
Common ground terminal.
5
OSCILLATOR
Aparallel RC network connected to this terminal determines the
switching frequency.
6
SOFT START
Soft start time constant. A capacitor is connected between this
terminal and ground to define the soft start time constant. This
capacitor also determines the average short circuit output
current.
7
OUTPUT
Regulator output.
