3. Limits established by characterization and are not production tested.
4. This is the maximum duty cycle achievable using the specified values of RTD and CT. Larger or smaller maximum duty cycles may be obtained
5. Adjust VDD below the UVLO stop threshold prior to setting at 7V.
6. When OUTx is delayed relative to OUTLxN (VADJ < 2.425V), the delay duration as set by VADJ should not exceed 90% of the CT discharge time
