5 / 15 page Electrical Characteristics (Notes 2, 9, 10) Limits in standard typeface are for T J = 25˚C. Limits in boldface type apply over the full operating junction temperature range (−30˚C ≤ T J ≤ 125˚C). 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: Feedback voltage specification for ADJ include the tolerances of the resistor divider network. ADJ configured to 1.5V output.
