It integrates a 1.2A switch and switches at 120kHz, making it suited for low-power applications where board space is not the primary constraint — the lower frequency demands larger external inductor and capacitor values compared to modern 1 MHz+ parts. The input range spans 2V to 9V, with the output adjustable from 1.25V up to 9V. This part is packaged in an 8-SOIC surface-mount package and rated for the commercial temperature range of 0°C to 70°C. ## Package and mounting Supplied in an 8-SOIC package (0.154\" body width, 3.90 mm wide) and listed in Bulk packaging — not Tape & Reel. If your assembly line is set up for reel-fed pick-and-place, Bulk tubes require manual loading or a tube feeder. The surface-mount footprint is standard SOIC-8; no special thermal pad is needed since the part dissipates modest power at the 1.2A switch limit.","metaTitle":"ADP1109AAR Step-Up DC-DC Converter, 120kHz, 1.2A Switch","metaDescription":"ADP1109AAR boost converter from Analog Devices.
