ISL9104, ISL9104A
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 = V EN = 3.6V, L = 1.0μH, C 1 = 4.7μF,
C 2 = 4.7μF, I OUT = 0A (see “Typical Applications” on page 2). Boldface limits apply over the operating temperature range,
-40°C to +85°C. (Continued)
