It supports multiple topologies — Flyback, SEPIC, Step-Down (Buck), and Step-Up (Boost) — giving you flexibility to match the LED load and input rail. Output voltage is rated to 100V, and the supply input range spans 6V to 100V, so it can run from a 12V automotive bus or a 48V telecom rail directly. Dimming is handled both ways: analog and PWM, which matters for color-mixing or brightness-control loops where PWM avoids color shift. The controller itself doesn't contain an internal switch — you add the external MOSFET and inductor, sizing them for your current and thermal budget. The 16-MSOP-EP package with exposed pad (0.118\" body, 3.00mm width) needs a good thermal land on the PCB to keep the junction within the -40°C to 150°C operating range. That temperature grade covers outdoor signage, automotive exterior lighting, and industrial LED arrays where ambient heat is a factor. ## Switching frequency and dimming flexibility The oscillator runs from 100kHz to 1MHz, set by a single resistor. Lower frequencies help with efficiency on high step-ratios; higher frequencies shrink magnetics and output capacitors. For LED loads, the True Color PWM™ topology keeps the average current regulation tight even at low dimming ratios, which is where analog dimming alone can drift with temperature. If you need both analog and PWM dimming on the same design, this part handles it. The PWM dimming input accepts an external signal, so you can synchronize dimming across multiple channels or with a microcontroller PWM output. ## Sourcing and lifecycle It's ROHS3 compliant, so it fits current RoHS requirements without exemption paperwork.","metaTitle":"LT3756JMSE-2#PBF DC DC Controller, True Color PWM LED Driver","metaDescription":"LT3756JMSE-2#PBF is an active LED driver controller from Analog Devices.
