It supports multiple topologies — Flyback, SEPIC, Step-Down (Buck), and Step-Up (Boost) — making it adaptable to various LED lighting architectures without changing the controller IC. The part provides both analog and PWM dimming, allowing the designer to choose between linear current control and high-frequency pulse-width modulation for color mixing or brightness stepping. Rated for an output voltage up to 100 V and a switching frequency adjustable from 100 kHz to 1 MHz, it targets applications such as automotive exterior lighting, industrial high-bay fixtures, and signage backlighting where tight current regulation and wide dimming range are required. ## 100 V rating and topology flexibility The 100 V maximum output and supply voltage set the ceiling for LED string voltage and input surge headroom. The switching frequency is adjustable from 100 kHz to 1 MHz. ## Active lifecycle and sourcing posture For new designs, this eliminates the risk of a last-time-buy window during the product development cycle. No second-source alternate is listed in the official record, so BOM planners should qualify the part as a sole-source item unless a cross-reference is independently validated. ## Temperature grade and environment The operating temperature range of -40°C to 125°C covers the full industrial and automotive cabin-grade span. The 16-MSOP-EP package with exposed pad aids thermal dissipation.","metaTitle":"LT3756IMSE-2#PBF LED Driver Controller, 100V, 1MHz","metaDescription":"LT3756IMSE-2#PBF DC DC Controller for LED drivers. 100V output, 100kHz-1MHz switching, analog & PWM dimming.
