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:
V
CC
over-
and undervoltage, mains undervoltage 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.
