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 Tech

Brief TB379.

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

Electrical Specifications Recommendedoperating conditionsunlessotherwisenoted. Refer to “BlockDiagram”onpage 5and “Typical

Application Schematics” on page 6. VIN = 4.5V to 60V, or VCC5V = 5V ±10%, C_VCC5V = 4.7µF, TA = -40°C to +125°C, Typical values are at TA = +25°C,

unless otherwise specified. Boldface limits apply across the operating temperature range, -40°C to +125°C.
