To support a typical inductor value of 1.5
H, the minimum inductance can go as low as 1.0H. It is not recommended to use a 1H
labeled inductor as the inductance will drop significantly below 1
H in operation due to initial tolerances and saturation.
ELECTRICAL CHARACTERISTICS
Unless otherwise noted: VIN1 = VIN2 = VCC = 5V, L = 1.5
H, COUTDCDCx = 10F, COUTLDOx = 2.2F, TA = –40°C to 85°C.
