Offline flyback LED driver, 1 A integrated switch
The Texas Instruments TPS92010D is an AC DC offline switcher in the TrueDrive™ series, built around a flyback topology and targeting lighting applications. It integrates the power switch internally, so the BOM stays lean — no external MOSFET needed for the primary side. Rated for 1 A output per channel, this single-output driver handles the current for a string of high-brightness LEDs in an offline luminaire. The 21 V supply maximum sets the bias rail ceiling; the internal switch and controller share that rail. Operating temperature spans -40°C to 105°C junction, which covers the ambient inside an enclosed outdoor or industrial light fixture where self-heating pushes the die temperature well above the board ambient.
No pin-compatible second-source or official successor is recorded — the TPS92010D is a single-source part from TI.
The supplier device package is 8-SOIC — the same footprint as the standard SOIC-8, so the PCB land pattern follows JEDEC MS-012.
