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 TB379
5. For
JB, the "board temp" is taken on the board near the edge of the package, on a copper trace at the center of one side. See TB379.
Analog Specifications VIN = VEN = 3.6V, VOUT = 3.3V, L1 = 1µH, C1 = 10µF, C2 = 47µF, TA = +25°C. Boldface limits apply across the
recommended operating temperature range, -40°C to +85°C and input voltage range (1.8V to 5.5V).
