NOTES:
3. Specifications at -40°C and 105°C are guaranteed by 25°C test with margin limits.
4. This parameter, although guaranteed by characterization or correlation testing, is not 100% tested in production.
5. SYNC pulse width is the greater of this value or the C
T
discharge time.
6. This is the maximum duty cycle achievable using the specified values of R

T
. Larger or smaller maximum duty cycles may be
obtained using other values for these components. See Equations 2 through 4.
