SD7510
Power Factor Correction CONTROLLER
Description Main feature Product specification classification Internal block diagram Technical documentation Relevant package outline drawing

      SD7510 is a high-performance power factor correction (PFC) controller primarily designed for boost topology, suitable for medium and high-power switching power supplies.

      SD7510 operates in critical conduction mode under heavy output load conditions and in discontinuous conduction mode under light output load conditions.

      Built with THD compensation functionality, SD7510 achieves excellent THD and power factor (PF) across the full load range.

      Equipped with input and output dynamic optimization features, SD7510 delivers outstanding dynamic performance and effectively reduces the variation range of dynamic output voltage.

     SD7510 integrates comprehensive protection functions, including output overvoltage protection, FB short-circuit protection, CS cycle-by-cycle overcurrent protection, and over-temperature protection.


Main feature

  • Operates in critical conduction mode and discontinuous conduction mode

  • Excellent load dynamic response

  • Optimized THD at light load

  • Ultra-low startup power dissipation

  • Output overvoltage protection and FB short-circuit protection

  • CS Cycle-by-cycle overcurrent protection and over-temperature protection
