    ... IC power supply problem when the output voltage is pulled down during standby mode, or during latch-off mode. The numerous protection functions give a full protection of the power supply system in failure situations. All of these make the ICE2QS01 an outstanding controller for quasi- resonant flyback converter in the market. Snubber C bus ...

    ... Functional Description 3.1 VCC Pre-Charging and Typical VCC Voltage During Start-up In the controller ICE2QS01, a power cell is integrated. As shown in Figure 2, the power cell consists of a high voltage device and a controller, whereby the high voltage device is controlled by the controller. The power cell provides a pre-charging of the VCC ...

    ... According to this information, the value in the up/down counter is changed to a low value in case of high regulation voltage, and to a high value in case of low regulation voltage. In ICE2QS01, the lowest value of the counter is 1 and the highest 7. Following text explains how the up/down counter value ...

    ... If the mains input voltage is high, the MOSFET on time will be short and the current limit will be low. In such a way, the maximum output power for the SMPS designed with ICE2QS01 will be nearly constant against the variations of mains input voltage. The current sense voltage limit versus the MOSFET maximum on time is shown in Figure 5 ...
