Electrical Characteristics (Notes 2, 9, 10) Limits in standard typeface are for T
J = 25C. Limits in boldface
type apply over the full operating junction temperature range (30C
≤ T
J
≤ 125C). Unless otherwise noted, specifications
apply to the LM3674 with V
IN = EN = 3.6V (Continued)
Note 11: Input voltage range recommended for ideal applications performance for the specified output voltages are given below
VIN = 2.7V to 5.5V for 1.0V ≤ VOUT < 1.8V
VIN =(VOUT +VDROP OUT) to 5.5V for 1.8 ≤ VOUT≤ 3.3V
Where VDROP OUT =ILOAD *(RDSON (P) +RINDUCTOR)
Note 12: ADJ configured to 1.5V output.
Note 13: For VOUT less than 2.5V, VIN = 3.6V, for VOUT greater than or equal to 2.5V, VIN =VOUT +1.
