The Infineon integrated power management IC with 800V avalanche rugged CoolMOS™, startup cell and QR current mode flyback PWM controller in DSO-16/12 package. Capable for 25.5W SMPS design. This derivative has a lower UVLO voltage (9.85V) so that it can easier be used to optimize system design. The quasi QR CoolSET™ 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. Integrated power IC with 650V avalanche rugged CoolMOS™, startup cell and QR flyback PWM controller
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
