† Notice: Stresses above those listed under “Maximum
ratings” may cause permanent damage to the device. This is
a stress rating only and functional operation of the device at
these or any other conditions above those indicated in the
operation listings of this specification is not implied. Exposure
to maximum rating conditions for extended periods may affect
device reliability.

Note 1: Wherever a specific VBST value is listed under test conditions, the VBST is forced externally with the
inductor disconnected and the DC-DC converter NOT running.
2: Typical values are for design information only.
3: Limits over the specified temperature range are not production tested and are based on characterization
data. Unless otherwise stated, production test is at room temperature with guardbanded limits.
4: Not production tested.
