It accepts a 4.2 V to 60 V input. ## 7.5 W output — what it can drive 7.5 W is enough for bias rails in motor drives, gate-drive supplies for IGBTs or SiC FETs, auxiliary housekeeping in telecom bricks, or isolated sensor power in industrial field transmitters. ## Wide input range and temperature grade The 4.2 V to 60 V input range handles cranking and load-dump transients on automotive buses without external clamping. The -40°C to 125°C operating temperature range suits under-hood automotive, outdoor telecom cabinets, and factory-floor enclosures. ## Fault protection and control features Built-in fault protection covers current limiting, over-temperature, and over-voltage — three common failure modes in isolated supplies. The enable (EN) pin and soft-start control let the system sequencer hold off the output until the upstream rail is stable, reducing inrush on the input bus. ## Package and rework considerations The 12-TDFN (3x3 mm) package has an exposed pad underneath for thermal dissipation. It is a surface-mount part, and the pad is the main heat path — make sure the PCB has a thermal via array under the part. ## Lifecycle and sourcing No end-of-life notice or last-time-buy window is in effect.","metaTitle":"MAX17691BATC+ Isolated Flyback Switcher, 7.5 W, 60 V Input","metaDescription":"Analog Devices MAX17691BATC+ isolated flyback switching regulator. 4.2 V to 60 V input, 7.5 W output, 12-TDFN package.

The key difference is that the MAX17691BATC+ includes an internal power switch (rated for 7.5 W), whereas the MAX17690 is a controller that drives an external MOSFET — so the MAX17691BATC+ saves board space and BOM count at the cost of a fixed power ceiling. Pin compatibility depends on the exact package variant; verify the footprint against the datasheet before substituting."},{"question":"What is MAX17691BATC+'s listed topology?","answer":"The listed topology is flyback, with output isolation built in. The internal switch handles the primary-side switching, and the secondary-side regulation is achieved without an optocoupler in basic isolated designs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX17691BATC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX17691BATC when reusing this data.
