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.
6. Per AEC-Q100-011 Paragraph 1.3.9, QFNs have no corner pins.
Electrical Specifications Refer to Figure 3 on page 7 and Typical Application Schematics (page 8). Operating conditions unless
otherwise noted: VIN = 12V, V_PVCC = 5.2V, and V_VCC = 5.2V, T_A = -40°C to +125°C (Note 8). Typicals are at T_A = +25°C.
Boldface limits apply across the operating temperature range, -40°C to +125°C.
