It takes an input from 2 V up to 9 V. ## Ratings that decide the fit The 1.2 A switch current is the hard ceiling. The 2 V minimum input means it can run from two alkaline cells in series. The 9 V input maximum keeps it off higher-voltage rails.","metaTitle":"ADP1109AAR-3.3 Boost Converter, 3.3V Fixed Output","metaDescription":"ADP1109AAR-3.3 step-up DC-DC converter, fixed 3.3V output, 1.2A internal switch, 120kHz switching, SOIC-8.

The ADP1111 series (ADP1111ANZ-5, ADP1111ARZ) can step up or step down, but the switch current is only 0.4 A, so it won't match the 1.2 A rating of this part."},{"question":"Can ADP1109AAR-3.3 output 5V if I change the feedback?","answer":"No — this is a fixed 3.3 V output version. The feedback network is internal and not adjustable.
