3. Typical values shown are not guaranteed. Guaranteed min/max values are provided in the SMD.
4. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
5. Limits do not include tolerance of external feedback resistors. The 0A to 6A output current range may be reduced by Minimum LXx On Time and
6. Limits established by characterization or analysis and are not production tested.
7. During an output short-circuit, peak current through the power block(s) can continue to build beyond the overcurrent trip level by up to 3A. With all six

power blocks connected, peak current through the power blocks and output inductor could reach (6 x 2.5A) + 3A = 18A. The output inductor must
support this peak current without saturating.
