FL7734MX
onsemiFL7734MX is the orderable code for onsemi's FL7734 primary-side-regulation (PSR) single-stage flyback LED driver controller, in SOIC-16 (150 mil) on tape and reel — for offline LED lamps and luminaires that need constant-current drive without an optocoupler or secondary-side feedback. The PSR control regulates output current from the primary side, cutting the feedback component count and its failure modes while suiting universal-input bulbs, tubes and retrofit lamps; the code is rated for -40 °C to +125 °C operation. Selection advice: FL7734MX is the complete ordering string from the onsemi datasheet ordering table — the bare family name alone does not specify the package or packing, so match the full MX code against your BOM. PSR accuracy is set by the flyback transformer turns ratio and the sensing network rather than by a feedback loop, so design those per the datasheet application section before committing the layout. The controller drew a 10,000-piece buy request on cecb2b, evidence of ongoing sourcing demand. Parameters verified against onsemi documentation.
