Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. Maximum electrical ratings are defined as those values beyond which damage to the device may occur at T
2. According JEDEC standard JESD22−A108B
3. This device series contains ESD protection and exceeds the following tests:
4. Latchup current maximum rating per JEDEC standard: JESD78.
5. JEDEC Standard: J−STD−020A.

TEST POINT
Maximum ratings are those values beyond which damage to the device may occur. Exposure to these conditions or conditions beyond
those indicated may adversely affect device reliability. Functional operation under absolute maximum−rated conditions is not implied.
Functional operation should be restricted to the Recommend Operating Conditions (Note 1).

Ground clip
To enable the buck converter, connect a shorting jumper between ENABLE−1 and ENABLE−2.
To disable the buck converter, connect a shorting jumper between ENABLE−3 and ENABLE−2.
A shorting jumper must be used to select an output voltage of 1.2 V, 1.5 V or 1.8 V
This is the positive connection of the output voltage.
This is the return connection of the output voltage.
This is the test point of the input voltage.
This is the test point of the enable pin.
This is the test point of the inductor voltage.
This is the test point of the output voltage.
