ISL8036, ISL8036A
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. (Continued)

NOTES:
6. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization and
are not production tested.
7. The operational frequency per switching channel will be half of the SYNC frequency.
