Overview
The FL7740MX, produced by onsemi, is a high-performance AC-DC LED driver designed to provide accurate Constant Voltage (CV) regulation. This component is particularly suited for smart lighting applications, offering differentiated dynamic functions to minimize overshoot and undershoot of output voltage during line and load transient conditions. The FL7740MX also features a low standby power consumption of less than 0.3 W and a high power factor of over 0.9, even at half load, when the PF optimizer is enabled.
