Functional Description
The ICE1QS01 is optimized to control free running flyback converters with and without Power Factor Correction (with PFC Charge Pump).
The switching frequency is reduced in small steps with decreasing load towards a minimum of 20 kHz in standby mode. This function is performed by a digital circuit to avoid any jitter also with periodically pulsed loads. To provide extremely low power consumption at light loads, this device can be switched into Standby Burst Mode. This is also possible without standby control signal (for adapter application).
Additionally, the start up current is very low. To avoid switching stresses of the power devices, the power transistor is always switched on at minimum voltage. The device has several protection functions: VCC over and under voltage, mains under voltage and current limiting. Regulation can be done by using the internal error amplifier or an opto coupler feedback. The output driver is ideally suited for driving a power MOSFET.
The ICE1QS01 is suited for TV-sets, DVD- sets, SAT- receivers and other consumer applications in the power range from 0 to app. 300 W.

Product Usage
The ICE1QS01 is an integrated circuit produced by Infineon Technologies, used primarily in the design of off-line switch mode power supplies (SMPS) that utilize a quasi-resonant (QR) or discontinuous conduction mode (DCM) flyback topology. Here are some common applications and circuits that use the ICE1QS01:
The ICE1QS01 is favored in these applications due to its ability to boost efficiency, reduce electromagnetic interference (EMI), and minimize power consumption in standby mode, making it well-suited for contemporary power supply designs demanding high efficiency and regulatory compliance.
