NOTE: 2. Refer to Appendix A3 for the Output Ripple and Noise Test Measurement Setup.

3. Output Power Derating applies at elevated temperature. See Appendix B for the Derating Curves.

4. OCP and OTP are in shutdown mode. The converter will auto restart without the need to recycle the

input voltage or toggle the enable signal and once the fault is removed.

6. Load step response shall be measured at the load side of the output capacitors. See Appendix A4 for

the output and input cap requirement.

7. See appropriate Trim Equation and configuration in Appendix A6.

8. The combination of remote sense and output trim adjust can not exceed 0.25V.

9. No OCP for Vo<1.5V. Module is protected by OTP when output is overload if Vo<1.5V.
