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.
θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
5. For
θJC, the “case temp” location is taken at the package top center.
6. All voltages are with respect to GND.
Electrical Specifications Recommended operating conditions unless otherwise noted. Refer to the Block Diagram on page 4 and
Typical Application schematics starting on page 5. VDD = 17V, RRAMP = 54kΩ, CRAMP = 470pF, TA = -40°C to +125°C, Typical values are at TA = +25°C.
Boldface limits apply over the operating temperature range, -40°C to +125°C.
