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:
1. 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.
2. θ JC , “case temperature” location is at the center of the exposed metal pad on the package underside. See Tech Brief TB379.
3. Parts are 100% tested at +25°C. Temperature limits established by characterization and are not production tested.
Electrical Specifications
Unless otherwise noted, all parameter limits are guaranteed over the recommended operating conditions and the
typical specifications are measured at the following conditions: T A = +25°C, V IN = 3.6V, EN = V IN , RSI = MODE =
0V, L = 3.3μH, C1 = 10μF, C2 = 10μF, I OUT = 0A (see “TYPICAL APPLICATION DIAGRAM” on page 6).
