Electrical Specifications Unless otherwise noted, the typical specifications are measured at the following conditions:
T A = -40°C to +85°C, V IN = 3.6V, EN1 = EN2 = VDD, L = 1.5μH, C1 = C2 = C4 = 2x22μF, I OUT1 = I OUT2 = 0A to 3A, unless otherwise noted. Typical values
are at T A = +25°C. Boldface limits apply over the operating temperature range, -40°C to +85°C. (Continued)
