Product details

What the 550kHz switching frequency means for your BOM

Fixed 550kHz switching frequency. 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. Enable pin provides on/off control. Single-phase, single-output. -40°C to 85°C operating range.

Frequently asked questions

Can LTC1872ES6#TRMPBF be used as a SEPIC controller?

Yes, the LTC1872 supports both Boost and SEPIC topologies. 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.

What is the difference between LTC1872ES6#TRMPBF and LTC1872ES6#PBF?

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.

What are the alternative parts for LTC1872ES6#TRMPBF?

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.
