3. Typical values shown are not guaranteed.
4. Limits do not include tolerance of external feedback resistors. The 0A to 6A output current range may be reduced by Minimum LXx
5. Limits established by characterization or analysis and are not production tested.
6. During an output short-circuit, peak current through the power block(s) can continue to build beyond the overcurrent trip level by
On Time and Minimum LXx Off Time specifications.
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.
