(1)

In the event of an output short or an overload condition, self-protection features lower the oscillator frequency to

≈18 kHz and the

minimum duty cycle from 5% to

≈2%. The resulting output voltage drops to ≈40% of its nominal value, causing the average power

dissipated by the IC to lower.

(2)

Output is not connected to diode, inductor, or capacitor. Output is sourcing current.

(3)

FEEDBACK is disconnected from output and connected to 0 V.
