This feature is only for module protection and is not intended for customer application. Th e value is specified at 25C ambient air temperature. For other ambient air temperature, please refer to thermal derating curve to determine corresponding current-limit inception values. 4. Pulse train with 90 ms period and 1ms pulse width. Average Iout equals about zero. 5. Input to Output Turn-On time is defined as the difference between t1 and t2: where t1 is the time when the input voltage reaches the minimum VIN (VIN = VIN,MIN) and t2 is the time when the output voltage reaches it's specified range (VO = VO,SET-Min). 6. There are two methods applicable to be able to trim the output voltage. Please refer to related sections under Feature Specification. 7. See Figure 6 for PGood configuration 8. Refer to further notes under Feature Specification for the Enable Pin function. 9. Check with factory for higher output capacitance loading. 10.
