NOTES: 1. The converter is not internally fused; an external fuse must be used.
2. Refer to Figure 1 for the input reflected ripple test setup.
3. Refer to Figure 2 for the Output Ripple and Noise Test Measurement Setup.
4. Measure output rise time from 10%VO to 90%VO.
5. Refer to the output trim equations provided (Equations 1 and 2).
