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:

4. JA is measured in free air with the component mounted on a high-effective thermal conductivity test board with direct attach features. See TB379.

5. For JC, the case temperature location is the center of the exposed metal pad on the package underside.

Electrical Specifications Refer to Figure 3 on page 7 and Typical Application Schematics (page 8). Operating conditions unless

otherwise noted: VIN = 12V, VPVCC = 5.2V and VVCC = 5.2V, TA = -40°C to +125°C (Note 7). Typical values are at TA = +25°C. Boldface limits apply across

the operating temperature range, -40°C to +125°C.
