Compare to LTC3872ITS8#TRPBF which adds Soft Start and Current Limit. ## Active lifecycle — no LTB risk for production builds Active product status, ROHS3 compliant. LTC1772BIS6#TRMPBF adds Buck and Flyback topologies. ## Designing with the LTC1872: external MOSFET and diode required Controller requires external N-channel MOSFET and Schottky diode.

The SEPIC configuration allows the output voltage to be above, below, or equal to the input — useful for battery-powered designs where the input varies across the output voltage."},{"question":"What is the difference between LTC1872ES6#TRMPBF and LTC1872ES6#PBF?","answer":"The difference is the packaging format. LTC1872ES6#TRMPBF ships in Tape & Reel (TR) or Cut Tape (CT), while LTC1872ES6#PBF ships in a different reel/tube format. The silicon, the TSOT-23-6 package, and all electrical specifications are identical."},{"question":"What are the alternative parts for LTC1872ES6#TRMPBF?","answer":"The LTC1772BIS6#TRMPBF is a functional alternative that adds Buck and Flyback topologies while keeping the same 550kHz switching frequency and TSOT-23-6 footprint. The LTC3872ITS8#TRPBF adds Soft Start and Current Limit and is rated to 125°C junction temperature."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LTC1872ES6TRMPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LTC1872ES6TRMPBF when reusing this data.
