It accepts an input from 2 V up to 30 V. ## What the ratings mean for the BOM Fixed 3.3 V output means no external resistor divider is needed — the feedback is trimmed inside. That saves two resistors and a potential noise pickup node on the feedback trace. Lifecycle status is Active — no end-of-life notice on record, no last-time-buy window looming. The RoHS compliance is listed as non-compliant, so this is a tin-lead (SnPb) finish part.","metaTitle":"ADP1108AR-3.3 DC-DC Converter, 3.3 V Fixed Output, 19 kHz","metaDescription":"ADP1108AR-3.3 step-up/step-down DC-DC converter from Analog Devices.

The part does not include a synchronous rectifier, so an external Schottky diode is required for the buck-boost topology."},{"question":"What is a suitable replacement for ADP1108AR-3.3?","answer":"A functional alternative is the ADP1111ANZ-5, which offers a fixed 5 V output in a through-hole package with a 72 kHz switching frequency. For a surface-mount adjustable-output option, the ADP1111ARZ provides a 1.2 V to 12 V adjustable output in an SOIC package. Neither is a drop-in replacement — verify the pinout, output voltage, and switching frequency against your design."},{"question":"What is the switching frequency of ADP1108AR-3.3?","answer":"The switching frequency is 19 kHz."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADP1108AR-3.3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADP1108AR-3.3 when reusing this data.
