That means it's engineered to work with standard wall-mount Triac dimmers (the kind in most residential and commercial dimmer switches) without the flicker or drop-out that plagues many retrofit LED drivers. If your lighting product is replacing an incandescent bulb on a dimmer circuit, this controller handles the phase-cut waveform and maintains stable output. No external dimming interface IC needed — the dimming logic is integrated into the switcher controller itself. ## Temperature range and environment Rated for a junction temperature range of -40°C to 125°C, this part is comfortable in outdoor lighting fixtures, parking-garage luminaires, and industrial high-bay lights where ambient temperatures can swing. The wide junction range also gives headroom for self-heating in a compact SOT-23-6 package — just make sure your external MOSFET and inductor are similarly rated if the fixture runs hot. ## Lifecycle and sourcing The TPS92075DDC/NOPB is listed as Active in production status and is ROHS3 compliant. The /NOPB suffix indicates lead-free (Pb-free) reflow compatibility, which is the standard for RoHS builds.","metaTitle":"TPS92075DDC/NOPB AC DC Offline Switcher, Triac Dimming","metaDescription":"TI TPS92075DDC/NOPB AC DC offline switcher for LED lighting with Triac dimming.

For 120V AC offline designs, the controller is typically powered from an auxiliary winding or a small bias supply derived from the rectified line — the part itself is an offline switcher controller, so it is intended for use with a rectified AC bus, but the 18V max on VCC means you need a bias supply that stays within that range."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS92075DDC-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS92075DDC-NOPB when reusing this data.
