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. JC, “case temperature” location is at the center of the exposed metal pad on the package underside.
Electrical Specifications Unless otherwise noted, all parameter limits are established across the recommended operating conditions and
the typical specification are measured at the following conditions unless otherwise noted: TA = -40°C to +85°C, VIN = 3.6V, EN = VDD. Typical values are
at TA = +25°C. Boldface limits apply across the operating temperature range, -40°C to +85°C.
