Digital high power factor controller serves flyback LED drivers

September 6, 2020  Stephen Law

INFINEON XDPL8219 XDP digital power, high-performance flyback controller features secondary-side regulation for high-performance and robust LED designs. Device provides high power factor and constant voltage output. Device operates in quasi-resonant mode (QRM) to maximize the efficiency and minimize the electromagnetic interference (EMI) over a wide load range. Product accommodates active burst mode (ABM) at light load to prevent audible noise while achieving a no-load standby power level below 100mW. Device detects the input voltage type (ac or constant dc) and adjusts its proprietary voltage-mode pulse modulator accordingly for enhanced system performance.
