The TPS92310-xxFB evaluation module is a constant current output LED driver supporting 5W to 8W applications. The design focuses on applications that require small form factor and minimal number of external components. The actual PCB dimension of the module is only 22 mm x 55 mm x 19 mm (L x W x H). The module can work with AC line input from 90 to 132 VRMS or 180 to 264 VRMS and supplying 350 mA current into a single string of LEDs, typically 6-7 LEDs in series. The evaluation board is carefully designed to comply with major industrial EMC and safety requirements. The user can make use of the information provided in this document, TPS92310 datasheet and application notes to design its specific end product easily.
