SLVS432D – SEPTEMBER 2002 – REVISED OCTOBER 2003
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can
range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to
damage because very small parametric changes could cause the device not to meet its published specifications.

Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may
degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond
those specified is not implied.
(2)
The voltage at the SW pin is sampled in PFM mode 15 s after the PMOS has switched off. During this time the voltage at SW is
limited to 7 V maximum. Therefore, the output voltage of the converter is limited to 7 V maximum.
