It supports four topologies — boost, buck, SEPIC, and flyback — so a single BOM position can serve a boost-configured high-bay light and a buck-configured sign backlight by changing only the external power stage. The controller lacks an internal switch, meaning the FET and inductor are external; this lets the designer size the power stage for the actual LED string voltage and current without being locked into a monolithic current limit. ## Dimming methods and switching frequency range Both analog and PWM dimming are supported, which is the standard combination for RGB color-mixing fixtures: analog sets the DC current floor, PWM modulates the on-time for color temperature blending without chromaticity shift. The oscillator runs from 100 kHz to 1 MHz, settable with a single resistor. At 1 MHz the inductor shrinks to a small footprint value for space-constrained PCBAs; at 100 kHz the switching losses drop, suiting higher input voltages or thermally limited enclosures. A single output drives the external gate driver — the controller itself does not carry the switching current, so the thermal dissipation stays in the external FET, not the IC. ## Lifecycle and compliance posture The tape-and-reel suffix (TRPBF) means it ships on 13-inch reels for automated pick-and-place; cut-tape quantities are also available for prototyping.","metaTitle":"LT3761AEMSE#TRPBF DC DC Controller, True Color PWM™","metaDescription":"LT3761AEMSE#TRPBF LED driver controller, 4.5-60V input, buck/boost/SEPIC/flyback, analog & PWM dimming, 16-MSOP-EP, RoHS3, active.

Both are True Color PWM™ controllers with analog and PWM dimming, no internal switch, and 1 MHz max frequency. If your board runs from a 5 V rail, the LT3761AEMSE#TRPBF is the fit; if the rail is 6 V or higher, the LT3796EFE#TRPBF is also an option but check the package — the LT3796EFE#TRPBF comes in a TSSOP-28 exposed pad, not the 16-MSOP-EP of this part."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LT3761AEMSE~4TRPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LT3761AEMSE~4TRPBF when reusing this data.
