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, “case temperature” location is at the center of the exposed metal pad on the package underside.
Electrical Specifications Unless otherwise noted, the typical specifications are measured at the following conditions:
TA = -40°C to +85°C, VIN = 3.6V, EN1 = EN2 = VDD, L = 1.5µH, C1 = C2 = C4 = 2x22µF, IOUT1 = IOUT2 = 0A to 3A, unless otherwise noted. Typical values
are at TA = +25°C. Boldface limits apply over the operating temperature range, -40°C to +85°C.
