Note 4

Coefficient

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.
