Exposure to such conditions may adversely impact product reliability and result in failures not covered by warranty. NOTES: 5. θJA 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 6. For θJC, the “case temp” location is the center of the exposed metal pad on the package underside. 7. LX1 and LX2 pins can withstand switching transients of -1.5V for 100ns, and 7V for 20ms. Analog Specifications VVIN = VPVIN = VEN = 3.6V, VOUT = 3.3V, L1 = 2.2µH, C1 = C2 = 10µF, TA = +25°C. Boldface limits apply over the operating temperature range, -40°C to +85°C.
