CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.
NOTES:
1. θ JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See
Tech Brief TB379 for details.
2. For θ JC , the “case temp” location is the center of the exposed metal pad on the package underside. See Tech Brief TB379 for details.
3. Test Condition: V IN = 15V, FB forced above regulation point (0.6V), no switching, and power MOSFET gate charging current not included.
4. Excluding the blanking time.
5. Specifications at -40°C to +85°C are established by +25°C test with margin limits.
Electrical Specifications
Unless Otherwise Noted, All Parameter Limits are Established Over the Recommended Operating Conditions
and the Typical Specifications are Measured at the Following Conditions: T A = -40°C To +85°C (Note 5),
V IN = 5.5V to 25V, Unless Otherwise Noted. Typical Values are at T A = +25°C.
