This is an isolated, 25W, 0-10V dimmable LED driver design with >0.9 power factor (PF) which meets or exceeds commercial lighting PF and total harmonic distortion (THD) requirements. It is well suited for integral LED luminaires, or ballasts, that use high-brightness LED emitters. This design is optimized for a 500mA (max) LED output current and LED stack voltages ranging from 45 V to 55 V.
