The high efficiency integrated power IC

The quasi-resonant CoolSET™ QR series continues to deliver design agility and miniaturization. Upon the successful F3 CoolSET™, this new series offer the possibility of higher efficiency and better EMI performance. The digital frequency reduction feature score a very stable operation with decreasing load change, and the fold-back correction keep the maximum power limits within tolerance desired by SMPS designers. The active burst mode operation during low power consumption, remains market leaders in providing best-in-class power consumption during standby.


The CoolSET™ QR provide the option as a solution for efficiency oriented SMPS industry.


Main Features
  • Integrated power IC
  • 650V /800V avalanche rugged CoolMOS™
  • 650V /800V startup cell
  • Digital frequency reduction with decreasing load
  • Cycle-by-cycle current limitation with fold-back correction
  • Built-in digital soft-start
  • Active Burst Mode for lowest standby power <50mW
  • Latch-off mode for short-winding and output voltage
  • Enhanced integrated protection functions
  • Modulated gate drive
