Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
4. The final switch current is: IIPK(0) / (Vin/LP + Sa) x Vin/LP + Vin/LP x tprop, with Sa the built−in slope compensation, Vin the input voltage, LP
the primary inductor in a flyback, and tprop the propagation delay.
5. NCP1072 130 kHz on demand only.
6. Oscillator frequency is measured with disabled jittering.
7. For coldest temperature, QA sampling at −40
°C in production and −55°C specification is Guaranteed by Characterization.
