Specifications at -40°C and +105°C although guaranteed, are not 100% tested in production. 4. This is the VCC current consumed when the device is active but not switching. Does not include gate drive current. 5. These parameters, although guaranteed, are not 100% tested in production. 6. This is the maximum duty cycle achievable using the specified values of RT and CT. Larger or smaller maximum duty cycles may be obtained using other values for RT and CT. See Equations 1 , 2, 3 and 4. Electrical Specifications Recommended operating conditions unless otherwise noted. Refer to Block Diagram and Typical Application schematicon page 2 and page 3. 9V < VCC = VC < 20V, RT = 11kΩ, Ct = 330 pF, TA = -40 to +105°C (Note 3), Typical values are at TA = +25°C (Continued) PARAMETER TEST CONDITIONS MIN TYP MAX UNITS Typical Performance Curves FIGURE 1.
