Product details

Active production, flexible topology

The LTC3411EMS#TRPBF is an active-production buck-boost regulator from Analog Devices, capable of step-down, step-up/step-down, or pure buck operation depending on the input-to-output voltage relationship. It delivers up to 1.25 A from a 2.625 V to 5.5 V input rail, switching at a fixed 1 MHz to keep external inductor and capacitor values small.

Supplied in Tape & Reel (TR) or Cut Tape (CT) for prototype or production volumes — the TR suffix on the order code indicates reel packaging for automated pick-and-place.

Sourcing and compliance

ROHS3 compliant, with no halogenated flame retardants or lead above the exemption threshold — the part ships with full material declaration for EU REACH and China RoHS reporting.

Frequently asked questions

What is the closest functional second-source for LTC3411EMS#TRPBF?

The ADP2301AUJZ-R7 is a buck-only regulator (1.2 A, 1.4 MHz, 3.0 V min input) in a similar footprint, but it lacks the buck-boost topology — it cannot regulate an output above the input voltage. The LTC3411EMS#TRPBF's buck-boost capability is the deciding factor when the input rail drops below the target output.
