GROUND

Common ground terminal.

5

14

OSCILLATOR

A parallel RC network connected to this terminal

determines the switching frequency. This pin must be

connected to pin 7 input when the internal oscillator is

used.

6

15

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.
