KP14503LGA is a linear constant-current LED driver IC designed for AC LED lighting applications. It integrates a 650V high-voltage MOSFET and provides a simple, compact solution for LED current regulation without requiring a complex switching power supply circuit.
The device supports ON/OFF segment dimming and allows adjustment of the segment ratio, making it suitable for color temperature tuning (CCT) and brightness adjustment applications. It provides accurate constant-current output with approximately ±5% current accuracy and supports multiple ICs operating in parallel for higher LED power applications.
KP14503LGA is mainly used in tunable white LED lamps, LED bulbs, and compact AC LED lighting solutions where a low-component-count linear driver is preferred.
