value is listed under test conditions, the V
BST
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.
