3. Output Power Derating applies at elevated temperature. See Appendix B for the Derating Curves.
4. OCP and OTP are in hiccup mode. The converter will auto restart once the fault is removed. OCP is not
precise with Vin varying . OTP along with OCP will protect the converter under typical overload
condition.
5. Measure output rise time from 10%V
6. Load step response shall be measured at the load side of the output capacitors. See Appendix A4 for
7. See appropriate Trim Equation and configuration in Appendix A6. The voltage difference between
input and output must be greater than 0.7V.
8. The combination of remote sense and output trim adjust cannot exceed 0.25V.
9. A tested correlation factor may be used to justify the minimum efficiency specification to facilitate
manufacturing test for the units under test with contact (non-soldering) type of connections, for example
pogo pin’s type of connection.
