SLVS294E – SEPTEMBER 2000 – REVISED AUGUST 2008 ........................................................................................................................................... www.ti.com
In case the converter operates in the forced PWM mode and there is no load connected to the output, the
converter will regulate the output voltage by allowing the inductor current to reverse for a short period of time.

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating
conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
