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:

JA 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

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

6. All voltages are with respect to GND.

Electrical Specifications Recommended operating conditions unless otherwise noted. Refer to “Functional Block Diagram” on page 2

and “Typical Application” on page 3. 17V < VPWR < 100V, CVSW = 1µF, IVSW = -3mA, VSW Enabled, TA = -40°C to +105°C (Note 7), Typical values are at

TA = +25°C.
