Note 1: Limits are 100% production tested at T A = +25°C. Maximum and minimum limits are guaranteed by design and
characterization.
Note 2: Regulation voltage tested with slope compensation. Typical value is equivalent to 0% duty cycle. In real applications, the
regulation voltage is higher due to the line regulation times the duty cycle.
