Infineon Technologies AG AC-DC PWM-PFC Controller, PWM-QR (quasi resonant) Flyback ICs ICE2QS02G

State-of-the-art Quasi Resonance current mode flyback PWM power control IC for power ranges up to 300 W. With innovative protection features for superior safety and reliability in operation. Of special note are its frequency modulation, its ultra low standby power consumption and an extensive array of protection features, allowing low EMI and highly efficient, reliable and cost effective designs. Without startup cell , it is good for main converter where the auxiliary power is provided. It has implemented with extra protection features such as brownout, adjustable blanking time for OLP,etc to suit for system requiremen

Summary of Features

• Digital frequency reduction with decreasing load for higher efficiency
• cycle by cylce peak current limitation, maximum output power limitation with input voltage compensation
• extensive protection features to protect the IC, brownout, adjustable blanking time for OLP and the system from various fault conditions e.g. output OVP latch, VCC OVP/UVP, OLP, Output OVP, Short-winding, etc.

Benefits

• Higher efficiency
• Low EMI noise, etc.

Potential Applications

• Main converter where the auxiliary power is provided such as LCD/PDP TV, color TV, etc.
