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. 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.
5. For θ_JC, the “case temp” location is the center of the exposed metal pad on the package underside.
6. Jedec Class II pulse conditions and failure criterion uses. Level B exception is using a minimum negative pulse of -1.2V on the
DPRSLPVR pin (#28).
Electrical Specifications
Operating Conditions: V_DD = 5V, T_A = -40°C to +100°C, f_SW = 300kHz, unless otherwise
noted. Boldface limits apply over the operating temperature range, -40°C to
+100°C.
