- Two-stage solution of boost APFC (based on YT8110FES8) + buck BUCK (based on YT2273YED7). Power factor (PF) > 0.95, total harmonic distortion (THD) < 10%. - Both the front stage and the rear stage integrate high-voltage start-up and power supply circuits. Under full load conditions, the start-up time is less than 11 ms. - Operating in quasi-resonant mode: high efficiency and good EMC performance. - Excellent line regulation: less than 1%. - Excellent load regulation: less than 2%. - Both the front stage and the rear stage support applications without auxiliary windings: the inductor manufacturing process is simple and the cost can be controlled. - Linear current reduction under over-temperature conditions: improving system reliability. - Complete protection functions: including output open-circuit protection, short-circuit protection, over-temperature protection, etc.
